How To Hire Freelance Developers With Optymize
In this digital age, companies and businesses need to outperform their competition and the internet is the best way for it. Even for a non-technical brand, having a website or application helps in connecting with the customers, sharing their product updates, and keeping them ahead of their seers.
But how should we hire freelance developers to build our websites? Why do we need them? For sure hiring freelance Developers has the benefit of being budget-friendly compared to an in-house team, but what else? Let’s read on to answer all your queries and guide you toward hiring freelance developers for your project and company.
Entrepreneurs and business professionals with an idea for innovative digital products need the right tech team to develop their vision. That’s one of the core reasons why many businesses are increasingly hiring freelance developers.
Developer outsourcing helps in saving time, regulates the budget, and increases focus on the other valuable aspects of the business. Even according to Deloitte, around 65% of businesses said that freelance outsourcing helps them in focusing more on the core functions.
Some major benefits of hiring freelance developers are:
- A freelancer costs significantly less than an in-house developer.
- Instead of looking for the right individuals from your local talents, you can hire from a larger pool of worldwide talent.
- Since they are working on a contract basis, freelance developers have better productivity than the employed developers.
- Project management tools also help in efficient communication, keeping everyone focused on the tasks, and complete deadlines.
- You can scale up and down the team members as per the changes in project development phases.
- Since you can hire more freelance developers at the cost of in-house developers, your project can be completed in less time.
Step 1. Identify Your Project Needs
You cannot start hiring freelance developers if you do not have clarity about the project or the role you are hiring for. Writing down all the project requirements will give you a clear idea of what you need. That includes considering the –
- The Platform
- The tech stack
- Project complexity
- Budget
- Timeline
- Team size as per the job role
Step 2. Choose the Right Model
There are broadly two models to consider while hiring freelance developers. The first one is to hire individual developers for short term projects or for a particular job.
The second choice is to hire a Freelance developer team. Hiring a team of pre-vetted experts is relatively easier as now you have every expert needed for every job.
After choosing a model, you need to look for these things to shortlist candidates-

- Years of experience and expertise: Now be specific about the role, technology needed for it and the number of years of experience in it. You can also opt for developers with expertise in multiple technologies.
- Projects in the past: You can shortlist and prioritize developers on the basis of their past works. Look for developers who have worked on similar projects as yours.
- Remote Work Experience: Developers with past freelance work experience can be a priority as they have first hand experience of working remotely, they can seamlessly communicate, and manage tasks at hand.
- Soft Skills: Communication skills are essential when hiring a freelance developer. As they are working remotely, they have to be efficient in communicating the progress, feedback, and collaboration with other team members and clients.
Step 4. Interview and Onboard Your Ideal freelance Developers
After selecting and hiring freelance developers, it’s now time to welcome them onboard. Some important points:

Here are some of the tools generally used by developers:
1. IDEs and Code Editors
Integrated Development Environments are a set of tools that provide everything that is needed for a developer to make programming easy and concise. A code editor has built-in features and functionalities to speed up the editing process. Sublime Text, Atom, Visual Studio Code are examples of these.
2. Inspection Tools
Code inspection tools enable developers to analyze their source codes, compiled codes to check for security faults and bugs. The developer can then fix the errors. Chrome DevTools, Raxis, and DeepSource are some common examples.
3. Git
Git is a code repository. A repository is simply a storage for the application or program a developer is working on. It can store the code, documentation, notes, web pages, and other important items. With these, developers can easily track their progress, use and modify previous versions and much more.
4. Build and Deployment
Deployment tools ease down the process to distribute and update software. They also help in scheduling, track progress, automation, manage changes, etc so the developers can focus on other tasks as well. Platforms like Docker, AWS code deploy, TeamCity are some best deployment tools we use.
5. Stack Overflow
Stack Overflow is a public forum for developers and engineers. Here, developers can ask any questions and the professionals will provide or help find solutions.
