Hire Back-end developers remotely within 3-5 days

When you’re looking for a freelance back end developer for hire, you want to ensure that you’re getting the best people for the job. But how do you know if the tech talent you’re hiring is good?

Professional backend developers are not easy to find. There are almost 200,000 job openings for developer positions in the US, and the competition for good backend developers is only increasing. Here’s what you need to know about the back-end developer’s position and how to hire back-end developers who will be a perfect addition to your team. 

Reasons Why Your Business Needs Backend Developers 

Back-end developers are in high demand, given their expertise in programming languages and technologies like C#/.NET, JS/Node.js, PHP/Laravel/Symfony, JAVA, GoLang, Python/Django/Flask, etc. To ensure that your business gets the best possible back-end developer on board, it’s crucial to know the value of their services. So: let’s figure out what they do in web development. 

If we were to break down the architecture of a web application, there would be two-part to it: the client part, with a web browser that sends a user’s requests to the server, and the server part, with a web server itself, but also business logic that underlies the UI that’s displayed within the web browser, and storage that contains the data a user is sending a request for. The first part covers the website’s UI, the interactable part of the resource; it’s constructed by front-end developers. Back-end developers for hire construct the second part, which means the following. 

Back-end Developers Create and Maintain the Business Logic of the App 

The business logic of the web app is the way software processes users’ requests. In other words, these are sequences that are activated when a user makes this or that request. If your website is, for instance, an e-commerce platform, business logic would contain different events that may or may not be triggered when a user tries to order something. Business logic would cover looking for an item, looking for a similar item, looking for the item with similar properties but lower costs, checking out the item, paying for it, and so on. 

Back End Developers Create and Manage the Storage and Work with Databases 

In a development team, back-end programmers also maintain the persistence layer of the web app architecture that accepts data calls from the users and establishes access to the app’s storage. Storage comprises of a server and a database, database management software, apps, and UIs that receive data and parse it. For the servers, back-end developers are often required to work with services that provide cloud storage, like Amazon or Google. 

Back End Experts Write Code to Maintain Security and Oversee 3rd-Party Components 

Back-end developers often establish secure means of communication and interaction with an app. They’re also usually in charge of integrating payment gateways and other third-party APIs a software would need to expand the software’s functionality. For instance, if you want to create software for hospitals, a back-end developer would need to create means of accessing this hospital’s EHR via EHR’s API. 

What Skills Do Backend Developers Have?

Back-end developers use back-end programming languages like PHP, Python, and Java to develop a website’s server-side functions. The purpose of a server-side scripts is to execute queries and process data while serving web users. They also write code that powers websites and online programs. 

But what exactly do these specialists do? Below is an overview of some of the key skills they possess.

Programming Languages and Frameworks

Backend developers should know at least one programming language like Java or Python before starting their career. It’s also great if they know frameworks that are based on their language of choice (Django for Python, Spring for Java, Ruby on Rails for Ruby, and so on) and utilize a toolkit that’s useful for their domain of choice. For instance, if it’s a developer with proficiency in integrating elements of machine learning into the web app, it would be great if they knew NumPy, scikit-learn, TensorFlow, or other tools that are created for ML tasks.

Database Management Systems

A freelance back end developer should know how to use the most popular database management systems like MySQL, Oracle, and PostgreSQL. You may also want to hire backend developer who knows NoSQL databases like HBase or MongoDB.

Version Control

Backend developers should be familiar with version control systems such as Git and Mercurial. Version control is an essential tool for tracking changes in software code, which helps the developer collaborate more effectively with other freelance developers on the team.

Web Hosting Platforms

Hire back-end developers who know how to use web hosting platforms like Amazon Web Services (AWS), Microsoft Azure, Heroku, and Google Cloud Platform (GCP). These are the frameworks that host your application and allow it to communicate with other systems over the Internet. 

Backend Coder Responsibilities 

The work of a back-end developer can vary depending on the project at hand, but in general, they are responsible for building web pages and APIs.

Back-end developers also build databases that provide storage capabilities for all this information.

What Tools Do Back-End Developers Use?

Back-end developers use a wide range of tools to develop, test, and maintain web applications. Here are some of the most common means of back-end developers’ work.

Programming Languages

Several programming languages are used for backend development. Some of the most common include:

• Python. A general-purpose programming language that’s used for web development, scientific computing, data analysis, and machine learning.
• PHP.  A server-side scripting language that’s primarily used for back-end development. It’s also one of the most popular programming languages on GitHub and has many frameworks available to help a PHP developer build web apps more quickly.
• JavaScript. A dynamic, object-oriented programming language that’s used by frontend developers, but can also be used for back-end development (Node.js).
• Ruby. A general-purpose programming language that’s known for being easy to read and write. 
• Java. A modern and object-oriented language with strong security uses, based on Sun Microsystems technologies.
• C#. A simple, modern, and powerful object-oriented programming language designed for building a variety of applications like video games or server applications. 

Those are some of the main languages that a back end developer uses, but this is far from a complete list.

Frameworks 

Frameworks are applications that allow you to build web apps more quickly than if you were to start from scratch. Here are some of the popular frameworks among backend developers:

• Laravel & Symfony. PHP frameworks that make it easy to build web applications. Symfony is best suited for large web apps that are heavily customized and Laravel is great for small projects, prototypes, and MVPs.  
• Django. A Python framework that provides an excellent set of tools for building web applications quickly and efficiently while avoiding many common mistakes that can lead to security vulnerabilities in your code base.
• Spring. A Java framework used for building enterprise-grade applications. The framework is primarily designed to support multiple programming languages like Java and Groovy, and the development of Model–view–controller (MVC) based applications. 
• Ruby on Rails. A full-stack web framework that provides an MVC structure, support for Ruby and SQL databases, and many other features.
• Meteor. A framework for building real-time web applications. It uses Node.js and MongoDB to provide a full-stack JavaScript solution, which enables the developer to write code in both client and server-side languages.
• Node.js. A server-side JavaScript environment that uses an event-driven architecture.

Hire back end developer who has a specialization in a programming language (e.g., Python) and at least one framework (e.g., Django/Flask).

Databases 

There are many different kinds of databases that a backend engineer can use. Some of them are: 

• MongoDB. A document-oriented database that stores data in JSON-like documents with dynamic schemas. It uses a flexible data model, which makes it easy to store and query JSON data.  
• MySQL. A relational database management system (RDBMS). It uses server/client architecture and is scalable, reliable, and transactional.   
• Oracle. A object-relational database management system (ORDBMS). An ORDBMS is similar to a relational database except that it also stores objects, which can be used as complex data types.

Databases like Oracle are often used in enterprise environments, where they can be used for large-scale applications.

Servers

Servers are used to store and run your web application (APIs). Some of the popular web servers:

• Apache. A free and open-source web server. It’s available for many operating systems, including Windows, Linux, and macOS.
• NGINX. A free and open-source web server that’s available for many operating systems. It can be used as a reverse proxy server or load balancer to distribute traffic across multiple servers. 
• Lighttpd. A free, open-source web server that supports HTTP and FTP protocols. It has built-in caching and is also available on various operating systems.
• Microsoft IIS. A Microsoft web server that can be used as a web application firewall. It allows administrators to configure their servers with a set of rules that are evaluated when an incoming HTTP request is received.

These are the tools that back-end developers use to make the magic happen.

Tips to Hire Back-End Developers

To hire back end developers who are good at their job, ask them about their past projects or clients. You can ask about backend programming languages and frameworks they’ve worked with before. Here are some tips you can use to hire backend developers with excellent skills. 

Company Needs

Decide whether you want to hire backend developers with extensive knowledge of a certain software, database, or programming language.

Programming Portfolio

If you are looking to hire backend developer with excellent skills, it’s important to find out if they have a portfolio. You can ask them to share their GitHub or StackOverflow profiles.

Coding Assessment

A coding assessment is one of the best ways to hire back end developers with good skills. You should ask them to take a programming assessment test like HackerRank or CodeWars. This will give you an idea about their coding capabilities and problem-solving skills.

Coding Interview

Another way to hire back end developer with good technical skills is by conducting a coding interview. You can ask them to write some code on the spot or solve a problem that you’ve given them in advance. Besides, you can ask a backend coder questions during an interview:

• What is your favorite database?
• How would you design a social network from scratch?
