Why Do You Need To Hire Developers

Posted on by Jay

A startup is the powerhouse of transformation and generation of value. If you are a startup and planning to make your business online with the help of web and mobile applications. It’s very important to hire developers to develop your application through which you will interact with visitors and convert them to the business.

Successful application development always helps your business growth. But It’s important to know whether you are on the right path or not.

According to a survey by Indeed on hiring managers and technical recruiters, 86% of the respondents have found it a challenge to find and hire developers.

The business that observes a lack of development support, might result in the failure of the business. If you are a founder that belongs to a non-technology background, it will help in transforming your idea into a high-performance app.

The programmers are not less than a wizard. They provide magical digital solutions by using coding, therefore it is important to hire a developer.

What should be considered before hiring a developer?

Before you plan to hire a developer, you need to look after several things such as:

Define what you want to develop?

It is one of the important things to look for before you start with the project. Such as on what project you are working?

Are you planning to hire web developers, mobile developers, or both?

To develop a digital solution for the web and mobile you need a native tool.

It is important to deliver a solution that can run both on the web and mobile. You need a developer who should be knowledgeable on hybrid mobile application development techniques.

Looking at the viewpoint of mobile solutions, you are required to decide between iOS and Android.

No overlaps take place in the application development. An android developer cannot be expected to develop an extensive and native iOS application.

Apart from this, both the iOS and Android application development requires different SDK.

Therefore it is important to find the platform in which you will get to run the application, before knowing about the process on how to hire a programmer for your startup.

Know your competitors and their products:

Once you decide on the platform, look for the existing solutions that work in the same field. To get a better solution and hire the perfect programmers for your startup, do proper research about your competitors.

The right solution is important to know before you hire a developer for your startup.

Once you prepare the solution, note down:

  • It’s features
  • What problems have to be solved?
  • Who are your ideal customers?
  • How are your competitors approaching your customers?
  • Identify the issue and problem.

Once you get your answer to all your problems, it helps you to understand the solution that you want to build.

As you understand the requirements of the vital application, hiring a software developer process will become easier.

Then, you will get a clear understanding on what to ask the developer to understand his/her skill-set.

Define the application and how it works?

To get the right programmers for your startup, develop a how-to-plan to get the solution?

Create a rough draft and note down everything for the operational sequence and solutions.

You can also draft a UI and UX mock-up of the application. It is imperative to get a programmer and show them what you can expect while working with your startup.

You can create a user journey and show how you can expect your user to engage with your solution.

All this information is necessary while choosing a developer for your startup. The next step you can do is note all the features that you want in your MVP version.

It will help you to assist while taking an interview. Some of the default features that are necessary for every type of application are:

  • Sign-up registration
  • Contact
  • Notification
  • Profile Creation

Except this, there are many solutions that provide specific features that have to be noted down.

Define the Value Proposition of your product:

To know the value proposition of your solution you need to focus on three things:

  • User Benefits
  • Relevancy
  • Differentiation

Developing a value proposition is imperative on both ends. If you are looking for a way on how to find a software developer for the end-user and startup.

Creating a value proposition will not make your solution look good. It will help in building real value for the customers.

Therefore share a mission, Value, and vision with the potential developers that will help to resonate your perspective.

Understand what you are looking for?

You need to remember two things

  • Software development is not the job of a single person.

If you hire a full-stack developer for the job, but a single person cannot execute all the work with      perfection.

  • Developing software is a no cut and dried for everyone.

It is important to identify the right developer and hire them for your startup.

Therefore, it is important to understand the profile, job description, and task requirements beforehand.

As there are different genres of developers, which becomes quite difficult in the hiring process. There are various subsets of developers. Some work in the backend and some work on the front-end.

Why Outsourcing is a Key Strategy to Prefer for a Startup?

When a startup faces difficulties in hiring the right developers, they should follow this major strategy of Outsourcing.

Outsourcing includes a variety of roles, niches and industries from sales and design to customer support and development. Some of the major reason to prefer outsourcing is:

Cultural Shift:

Most of the business and teams do not feel comfortable in working with the remote teams because of the time zone differences, various working habits such as working in remote locations. Since the Covid-19 pandemics employees have started working with defined goals and follow a certain agenda during their working hours. The teams are able to meet up the goals which supersedes all other expectations.

Fastest On boarding:

Many service providers are expertise and experienced and are available to get hired in a very short notice. It states that you get access to an experienced talent pool with demand and it reduces the efforts used in hiring, retaining and on boarding process. That is required but not needed for long term work.

Competitive:

With Outsourcing, the cost to hire a developer requires less time. Therefore, sourcing the right expertise for your project with competitive cost will save 2.5X cost on new technologies.

The service providers give proper training to their resources on all the new and emerging technologies which will provide many advantages.

What are the challenges in hiring a developer?

Here are major challenges in hiring the developers:

  • New developers often hesitate with lots of backend customization.
  • Difficulties in regular update with the information.
  • No built-in backup systems.
  • Slow loading page due to external plugins.
  • Worried about the security holes for hacking

“Hiring the right tech team in the early stages of your startup is potentially going to be one of the cornerstones of your success. If you’re not a founder who is experienced in tech, it can seem almost insurmountable. However, you have to put in the effort into taking the correct hiring decisions because this is one thing you have to get right.”                                                                                 -Paul Graham, Founding Partner of Y Combinator

Solution of Hiring a developer for your startup:

Globally start-ups companies are facing major challenges in developing world-class products and applications which are loved by their users and they get hooked to it.

Therefore by hiring a dedicated developer will provide you with many benefits such as:

  • Dedicated developers: You can hire dedicated developers that are highly skilled and expertise in developing applications. Hiring dedicated developers might be difficult therefore you can take the help of professional web and mobile application development services like Andolasoft, who offer high quality development services.
  • Risk Mitigation: When you get to hire an experienced dedicated development team for your dream project, they get all the things done by identifying the risk regarding transitions and operations. You don’t have to worry about doing things all by yourself that you don’t know how to do. Therefore hiring a development team will help you deliver risk-free results.
  • Access to many skills: As certain projects need certain skills. When you hire a team of developers, you don’t have to carry the burden all by yourself. You get access to get broader skills, expertise, knowledge, and solutions to build the product.
  • Sure result: If you hire a development team, they follow the best practices to build a product. This results in improving productivity right from the beginning of the project. Likewise, when the team has proven experience in developing similar projects, you are assured of the outcome of your project.

Where to look for the Developer?

You will get your software developer at a specific place. A lot of hiring agencies and online platforms are there from where it became easier to hire a developer even for a startup company.

According to a CB Report- 23% of the startup companies are failing because of their inadequate team. Also, working alone on the development process will take 3.6x times longer to make it successful.

Consider these two aspects before you hire developers for a startup. It states that a single person cannot work alone and if you have a team then it turns out to be good.

You can get your Software developers through offline and online modes. Various job portals and social media platforms have become an efficient mode to find your required and dedicated developers.

You can also get your developers offline through meetups, co-working spaces, hackathons, and various other platforms.

To move forward, you need to understand the importance of a software developer for your startup.

Your digital solution is your dream, and you have worked day and night to gather enough resources to fulfill that dream.

So, you cannot share your dream with just anybody. No! You need to implement the most comprehensive hiring structure for a startup.

We all know that maintaining a competitive edge in this race is quite harder for any business.

You must have acknowledged, many entrepreneurs are upgrading their business stores to the online market. And some are even pushing their industry services to the mobile platform as well.

In order to get your success, you just need to charm your plans and put something extraordinary  into it.

As an example- if you are choosing a mobile app development plan, then you must be aware of how much the mobile sector is constantly getting a good response. So,

  • Do you have enough budgets for it?
  • Are you sure that your business idea is viable?

You found an excellent idea for a startup and you want to turn that into reality. But building even the simplest product needs investment, which is now a major challenge for every entrepreneur.

However simple or complex, it’s obvious to validate that idea to ensure all your investment doesn’t go to waste.

So, What’s The Best Way To Validate The Idea?

The answer is MVP.

Most of the starting up business starts with the MVP development before moving on to the full-fledged web product. Well, this is the right step as it minimizes the risk of product failure upon its launch.

In simple words, it helps to find out whether you should move ahead with the idea to develop the product or not.

But Who Is Going To Will Build The MVP For Your Approach?

Well, here’s the thing…

If you’ve required technical knowledge, then without wasting much time, you should go ahead and start building your MVP. But, what if you are a non-technical entrepreneur? Hire a full-stack developer rather than relying on anyone else.

Now before you rush in finding full-stack developers all over the web, it’s vital to understand

Who Exactly The Full-Stack Developers Are?

In simple words, a full stack developer is a jack of all trades developer. They are well-aware of most of the technologies to build an entire application.

They can work on both front-end and back-end development. In the app development industries, full-stack developers are stood as T-shaped professionals.

The frontend is everything that is observed by end users and the place where they directly interacts with, unlike sign-up page or the site in the online store

T-Shaped Professionals?

The name T-shaped was given because, unlike traditional I-shaped professionals who are professionals only in their own domains but have no idea about others, a full-stack well developer is a professional in one or two different domains and knows about other domains as well.

T-Shaped ProfessionalImage Souce: Whatech[.]com

In simple words, a full-stack developer can be an expert in one or two front-end and back-end technologies. They also can possess functional skills of languages beyond their main expertise.

So when it’s about developing an MVP for your business, these T-shaped professionals are the perfect fit.

How MVP Is Helpful?

Suppose you want to develop an E-commerce app. The designs are ready and all you need is to get its MVP built.

So, the first thought may come to your mind to hire in-house developers which might be different professionals for different skill-sets. Such as:

  • UX Designer
  • Front-end Developer
  • Back-end Developer
  • Quality Analyst

But, the expenses of each individual are always going to differ. If you want to go with this, then the first obstacle will be the communication between you and the hired dedicated developers, will be chaotic.

Full-stack developers can manage the MVP development effectively. They can fulfill all the development aspects such as quality analysis, UX designing, front-end, and back-end development.  

Full-stack development mainly consists of 3 layers, such as;

  • Presentation Layer
  • Business Logic Layer
  • Database Layer

Presentation Layer:

This is the frontend of an application or product. In this layer, the UI is designed and developed. That means your full-stack developer must have the basic knowledge in CSS, HTML, and JavaScript.

That’s not enough. That developer must be well-known to the latest JavaScript framework. Hence, while searching for full-stack developers, make sure that the selected candidate must be experienced in using Angular.js, Vue.js, and React.js.

Business Logic Layer:

This is the backend of an application or product which strengthens the frontend. In this layer, the full-stack developers use server-side programming languages to write the business logic of the product or application.

So the chosen full stack developer must know the backend frameworks such as Node.js, Ruby on Rails, Python with Django, and Java with Spring MVC.

Database Layer:

The database is a part of the backend and your full stack developer must be comfortable with both relational as well as Non-relational databases.

Relational databases generally use tables to store data, while Non-relational databases store data in JSON format. And right now, there are mainly three popular database languages: MySQL, MongoDB, and PostgreSQL.

So these are the basic things that required for full-stack development, and to leverage the development process, there must be a skilled developer to archive the real objects.

Now, you can say the full stack developers are real-life superheroes. Isn’t it?

Of course yes!

Let’s see, what are the real benefits of hiring a full-stack developer in MVP development.

  • Cost Saving– This is obvious. It costs a lot to hire individual specialized developers than a full-stack developer.
  • Easy To Upgrade– Compared to other developers, full-stack developers are more friendly and adaptive to the latest technologies. In case if your MVP needs any kind of technical changes; a full-stack developer can learn the scenario and will manage quickly.
  • Easy Switching– Any experienced and skilled full-stack developer can switch between back-end to front-end and vice-versa easily.
  • Fast And Perfect Delivery– The full stack developers can work as an individual unit. This makes the entire project development process easier as the developers divide the work responsibility among each other equally and coordinate well to bring out the best results.

What Are The Essential Skills Present In A Full Stack Developers?

A full stack web developer jobs required lots of skills and knowledge. So here is a list of the important skills required in a Full Stack Developer job:

  • Backend language: A Full stack developer need to build both part of the application. Therefore they need to have backend knowledge like PHP, Python, Ruby, Java.
  • Javascript: A Full stack developer is covered with various knowledge on programming languages. As many tech specialist see Javascript as an important skills for a full stack developer, used for adding behaviour via HTML.

GIT and GITHUB: There is no developer who has no knowledge on GIT and GITHUB. As GIT is a popular version control system. It allows the programmer to track all the changes done in the application and streamline the work within the development team.

The Idea of hiring the full stack developer or team is something like to work closely with your requirements, practical, easy to handle which would help your business to run successfully online. A technology partner like Andolasoft will help to accelerate your business growth, get access to the best talent pool.

4 Simple Steps To Implement “Delayed Job” In Rails

Posted on by Jay

Here in this article, I going to tell you the best way to implement “delayed job” in rails

“delayed_job” is a ruby gem used to execute tasks as a background process in Rails environment, increasing page rendering speed.

Delayed::Job (or DJ) allows you to move jobs into the background for asynchronous processing.

Why you need a background process and is it really that important!

Let’s consider a scenario where a mailing application needs to send emails to a huge list of recipients. In such cases it is obvious that the processing time is too long, annoying the users.

Here are some of key points to consider:

  • Incredibly quick & easy to get rolling
  • No addition to your “stack”, runs just fine with Active Record
  • Good choice for beginners while migrating code from foreground to the background

Hence, it’s only wise to move the long running tasks as a background process by using “delayed_job” gem.

Detailed steps to integrate delayed job in a Rails application

Step# 1

  • Add gem to the Gemfile
  • “delayed_job” supports multiple back-ends for storing the job queue
  • To use “delayed_job” with Active Record, use gem ‘delayed_job_active_record’
  • To use “delayed_job” with Mongoid, use gem ‘delayed_job_mongoid’

Example

/Gemfile.rb

  • gem ‘delayed_job_active_record’, ‘4.0.3’
  • Run “bundle install” to install the “delayed_job” gem

Step# 2

  • Generate the related file for the Job run
  • Generate related files required to run the background job by running the following command
    • rails g delayed_job:active_record

It adds following files to the application

  • A Script named “delayed_job” inside “/bin” folder to run the jobs which are in queue.
  • Migration file to create a table to store the job with other information such as priority, attempts, handler, last_error, run_at, locked_at, failed_at, locked_by, queue.

Run the migration file by using the following command

  • rails db:migrate

Set the queue_adapter in config/application.rb

  • config.active_job.queue_adapter = :delayed_job

If you are using the protected_attributes gem, it must appear before delayed_job in your gemfile. If your jobs are failing with:

  • Setup Delayed::Job config in an initializer (config/initializers/delayed_job_config.rb)
    • Delayed::Worker.destroy_failed_jobs = false
    • Delayed::Worker.sleep_delay = 60
    • Delayed::Worker.max_attempts = 3
    • Delayed::Worker.max_run_time = 5.minutes
    • Delayed::Worker.read_ahead = 10
    • Delayed::Worker.default_queue_name = ‘default’
    • Delayed::Worker.delay_jobs = !Rails.env.test?
    • Delayed::Worker.raise_signal_exceptions = :term
    • Delayed::Worker.logger = Logger.new(File.join(Rails.root, ‘log’, ‘delayed_job.log’))

Step# 3

  • Replace script/delayed_job with bin/delayed_job
  • Start up the jobs process

There are two ways to do this.

  • If application is in development mode, we would use the below rake task instead.
    • rake jobs:work
  • If application is in production mode, then it is preferred to use the “delayed_job” script. This demonizes the job process and allows multiple background processes to be spawned.

To use this, pursue the following steps

  • Add gem “daemons” to your Gemfile
  • Run bundle install
  • Make sure you’ve run rails generate delayed_job
  • If you want to just run all available jobs and exit you can use rake jobs:workoff
  • Work off queues by setting the QUEUE or QUEUES environment variable.
    • QUEUE=tracking rake jobs:work
    • QUEUES=mailers,tasks rake jobs:work

Step# 4

  • Add task to run in background
  • In Controller just call .delay.method(params) on any object and it will be processed in the background.

Example:

UsersController before adding to background job

[code language=”html”]
class UsersController < ApplicationController
def send_email
User.find_each(is_subscribed: true) do |user|
NewsMailer.newsletter_mail(user).deliver
flash[:notice] = "Mail delivered"
redirect_to root_path
end
end
end
[/code]

 
UsersController after adding to background job

[code language=”html”]
class UsersController < ApplicationController
def send_email
User.find_each(is_subscribed: true) do |user|
# add .delay method to add it to background process. In case of mail sending remove the .deliver method to make it work.
NewsMailer.delay.newsletter_mail(user)
flash[:notice] = "Mail delivered"
redirect_to root_path
end
end
end
[/code]

Advantages of implementing above steps:

  • No more waiting for a response, after clicking a link to do a big stuff.
  • Just call .delay.method(params) on any object and it processes in the background.
  • Job objects are serialized to yaml and stored in the delayed_jobs table, so they can be restored by the job runner later.
  • It automatically retries on failure. If a method throws an exception it’s caught and the method reruns later. The method retries up to 25 times at increasingly longer intervals until it passes.
  • “delayed_job” gem maintains log by creating a log file “/log/delayed_job.log”

I am sure this article will give you a clear idea about the way to implement “delayed job” in rails. You can share your thoughts with comments if I have missed anything or if you want to know more.

How To Implement Event Calendar In Rails App

Posted on by Jay

Event calendar is a way to show multiple, overlapping events across calendar days and rows. This is an interface to add events, edit events, & destroy event. In Rails there is a gem/plugin “event_calendar” to implement it just like Google calendar.

The following steps demonstrate the implementation of event_calendar in both Rails 2.3.x and Rails3.x environment.

Step#1 –

Installing the gem/plugin

  • In rails 2.3.x

Install the required plugin from below path

script/plugin install git://github.com/elevation/event_calendar.git

Generate the necessary static file and example

script/generate event_calendar
  • In rails 3.x

Install the required gems

gem 'event-calendar', :require => 'event_calendar'

Run “bundle install”

You can also use as a Plugin, to install plugin

rails plugin install git://github.com/elevation/event_calendar.git

Generate the necessary static file for the event calendar

rails generate event_calendar

Step#2

Include the necessary style sheet & java-script into your layout/view

<%= stylesheet_link_tag "dialog","fullcalendar","jquery-ui","style" %>
<%= javascript_include_tag "jrails1/fullcalendar.js","jrails1/jquery-
ui.js","jrails1/gcal.js","jrails1/jrails.js","jrails1/jquery.validate.js"%>

Step#3

Create a migration file to add necessary columns as follows

class CreateEvents < ActiveRecord::Migration
def self.up
create_table :events do |t|
t.string :name
t.datetime :start_at
t.datetime :end_at
t.timestamps
end
end
def self.down
drop_table :events
end
end

Step#4

Add the necessary paths to the “config/routes” file

  • In Rails 2.3.x
map.calendar '/calendar/:year/:month', :controller => 'calendar', :action => 'index',
 
:requirements => {:year => /d{4}/, :month => /d{1,2}/}, :year => nil, :month => nil
  • In Rails3.x
match '/calendar(/:year(/:month))' => 'calendar#index', :as => :calendar, :constraints => {:year => /d{4}/, :month => /d{1,2}/}

Step#5

Change the Event model to add the calendar as follows

class Event < ActiveRecord::Base
has_event_calendar
end

Step#6

Modify the Calendar controller as follows

class CalendarController < ApplicationController
def index
@month = (params[:month] || Time.zone.now.month).to_i
@year = (params[:year] || Time.zone.now.year).to_i
@shown_month = Date.civil(@year, @month)
@event_strips = Event.event_strips_for_month(@shown_month)
end
end

Step#7

You can also override the events method in helpers/calendar_helper.rb

module CalendarHelper
def month_link(month_date)
link_to(I18n.localize(month_date, :format => "%B"), {:month => month_date.month, :year => month_date.year})
end
# custom options for this calendar
def event_calendar_options
{
:year => @year,
:month => @month,
:event_strips => @event_strips,
:month_name_text => I18n.localize(@shown_month, :format => "%B %Y"),
:previous_month_text => "<< " + month_link(@shown_month.prev_month),
:next_month_text => month_link(@shown_month.next_month) + " >>"
}
end
def event_calendar
calendar event_calendar_options do |args|
event = args[:event]
%(<a href="/events/#{event.id}" title="#{h(event.name)}">#{h(event.name)}</a>)
end
end
end

Step#8

Add the following code to display the calendar in the view file

<%= event_calendar %>

How To Generate Barcode Using Barby Gem In Rails 2.3.8

Posted on by Jay

A barcode is a series of vertical black lines with white spaces in between. This series of lines and spaces can be read by a device that can decode them. This would be a barcode reader.

In Ruby on Rails there is a gem called “barby” which generates the barcode with various format.

Here is an example to create barcode using barby & Rails 2.3.8.

Step#1

Include the barby gems in your config/environment.rb file

config.gem'barby'
config.gem 'barby-chunky_png'
config.gem 'png''RubyInline'

Install the gems by running the commandrake gems:install. Restart the Rails server.

You might face problem to start the server after the gems installed.Comment out the gems “png” & “RubyInline” in the “config/environment.rb” to get the server started.

Step#2

Create a folder named “Barcodes” to store the barcode images in your “Public” folder.

Step#3

Add the below lines of code in your controller

require'barby'
'barby/outputter/png_outputter'

Step#4

The following method will generate the barcode images and store in the “/public/Barcodes” path. Place this method inside the controller.

The “symbology” is the format in which the barcode will be generated. Default is “Code128B”, If you want to generate in different format you can set the “symbology” according to it.

def generate_barcodes(data) # check to see if we don't already have this barcode image uri = CGI.escape(symbology) + '_' + CGI.escape(data) + '.jpg' fname = RAILS_ROOT + '/public/Barcodes/' + uri #fname = '/var/www/html/arc_cloud/arcdevelopment/' + uri
 
# if the barcode image doesn't already exist then generate and save it
if ! File.exists?(fname)
 
str = 'Barby::'+symbology+'.new("'+data+'")'
 
begin
barcode = eval str
rescue Exception => exc
barcode = Barby::Code128B.new(data) # fall back to Code128 type B
end
 
File.open(fname, 'w') do |f|
f.write barcode.to_jpg
end
 
end
uri
end

Step#5

Following lines of code will call to generate your dynamic barcode
generate_barcodes(@item_id)

Step#6

To show the Barcode images call the following lines of code

<img src="/Barcodes/<%= @job_info.job_number %>.jpg" >
