How to Hire Freelance Backend Developer

Ever wondered what goes on behind the workings of a website? Back-end development refers to the specific development of server-side logic that effectively runs websites and mobile apps from behind the scenes. It typically includes all the code required to build out the server, database and application. 

Back-end developers are the experts who are responsible for building and maintaining the mechanisms that process the data and perform the actions on websites. Unlike front-end engineers who control everything you see on a website or app, back-end developers work with data security, storage and other server-side tasks that cannot be seen.

In a team, back-end developers usually collaborate with front-end developers, principal architects, product managers and website testers to create the general structure of a website or app. Back-end developers must ideally be familiar with many different kinds of frameworks and tools, including languages such as Java, Python, and Ruby. They are responsible for making sure the back-end of a site or app performs quickly and responsively to different front-end user requests.

5 Tips to Recruit a Qualified Freelance Backend Developer

Hiring a qualified backend developer is an integral part of the success of your software development project. But whether you’re an old hand at hiring developers or new to the game, it can be a daunting task to select the perfect candidates to join your ever-growing team and to make sure you get the results you are looking for. Here are a few important tips to ensure you’re hiring backend developers effectively: 

  • Employment level

First and foremost, it’s important to decide whether you need an entry-level backend developer or someone who can fulfill a more senior role. A senior developer or team leader will be managing a team of developers and, therefore, you need someone with prior experience and leadership skills. A junior developer has the experience but will be working as part of a team, so it is important to establish that they can get along with co-workers and follow instructions. 

  • Available budget

Once you have decided what level of backend developer you require, you will need to establish a market-related budget available for the position. It is important to note that the more you are willing to pay, the better a developer you will most likely be hiring. Although, you also need to be mindful of your overheads and having the best developer in the world does not necessarily translate to profit. As with all things business, negotiation is often warranted. 

  • Available resources

There are countless hiring platforms online where you can look for qualified backend developers that will suit your needs and the budget you have available. The great advantage of using a recruitment company is that candidates are already vetted and easily onboarded. 

  • Remote or in-house

It is important to decide whether you need a team that works in your physical office or remotely. There are many different pros and cons to each of these hiring models. Remote teams can be more affordable, while in-house teams are accessible. 

  • Vetting

If you decide to hire developers yourself instead of utilizing a recruitment agency, it is non-negotiable to vet the candidates. During the vetting process, it’s important to ask for previous projects to check the quality and accuracy of work completed. It’s also essential to include interviewing and testing stages. 

The Most in-demand Tech Stacks Among Freelance Back End Developer Candidates

A tech stack refers to the combination of technologies developers use to build a website or application. Tech stacks consist of frameworks, programming languages, databases, front-end and back-end tools, and applications connected through APIs. Let’s take a look at some of the tech stacks most popular among backend developers: 

  • Programming languages

These languages create logic for websites and apps. The codes created by these languages link websites and apps to a database. Some examples include PHP, JavaScript, and Python.

  • Frameworks

Frameworks provide support for apps based on single programming languages. Django, Laravel and Ruby on Rails are a few of the most popular backend frameworks. Modern applications are often built using an MVC-style framework.

  • Web Servers

Freelance back-end developer candidates use backend servers to manage client requests. Some of the most common web servers include Nginx, Apache, and Microsoft’s Internet Information Server (IIS).

  • Databases 

Most applications need an SQL or NoSQL database. Common databases include MongoDB, PostgreSQL, and MySQL.

The Most Valuable Soft Skills of Backend Developer Freelance Experts 

The best part time backend developer experts possess specific hard and soft skills. It is important to consider these skills before hiring candidates to ensure you recruit the best talent for your project. Here are a few of the most crucial soft skills to look out for when you are looking to hire back end developer experts: 

  • Communication skills

Communication is key in any business and for all employees, no matter the industry. Backend development requires freelance backend web developer candidates to be able to communicate with their team and management to convey any updates and progress. Ideally, they should have excellent verbal and written communication skills to ensure transparency and avoid misunderstandings. 

  • Ability to problem solve

Developers will often encounter problems throughout the lifecycle of a development project. How they deal with these problems and solve them is what sets developers apart. The very best backend developers can easily identify concerns and find solutions before they become bigger problems. 

  • Time management

Development projects often work around tight deadlines. As a result, freelance back end web developer candidates should be able to manage their time carefully and stick to set deadlines. 

  • Ability to work with others

Backend developer part time experts often work as part of a team. So, they need to be able to collaborate with others effectively and efficiently.

  • Critical thinking and creativity

Because development these days needs to be innovative to stand out online, back-end developers need to be excellent creatives and critical thinkers. They need to find unique solutions and come up with creative ideas for every project. 

  • Ability to self-motivate

Coding can be a time-consuming task. As a result, back end developer freelance candidates need to be able to motivate themselves without needing inspiration from management. 

  • Ability to manage

Often, back-end developers have to lead a small team. So, they need to be able to manage people and delegate tasks without needing to be micromanaged. 

An Overview of the Best Sites to Hire Part-time Freelance Backend Engineer Candidates
