FAQs

What are the main skills I should look for when hiring a freelance fullstack engineer?

You should look for skills in both front-end and back-end development. A fullstack engineer should know languages like JavaScript, HTML, and CSS for front-end work. They should also be familiar with databases and server-side languages like Node.js or Python for back-end development.

Why is it important to define project deliverables before hiring?

Defining deliverables helps both you and the engineer understand what needs to be done. It sets clear expectations from the start of the project. This way, everyone knows what the end goal is and can work towards it together.

How can I ensure the freelance fullstack engineer understands my project?

Share a detailed project brief that outlines your goals and objectives. Include any technical specifications or requirements you have in mind. This ensures the engineer knows what you want and can plan their work around it.

What should be included in a timeline for a freelance project?

A timeline should include key milestones and deadlines for when work needs to be completed. It helps keep the project on track. Make sure to discuss this timeline with the freelancer to ensure it's realistic.

How do I verify a freelancer's portfolio when hiring through Contra?

Review the freelance engineer’s past projects and case studies. Look for projects similar to yours and ask for client testimonials if available. A strong portfolio showcases their skills and ability to deliver quality work.

Why is a trial period useful when working with a new fullstack freelancer?

A trial period lets you see how the freelancer works and solves problems. It gives you a chance to evaluate their skills before committing to the full project. This helps build trust between you and the engineer.

What communication tools should I use to stay connected with the freelancer?

Use tools that allow for regular check-ins and updates like email, chat platforms, or video calls. Consistent communication keeps everyone on the same page. This helps catch and solve any issues early in the project.

How can I make sure the freelance fullstack engineer sticks to the project timeline?

Set up regular progress meetings to review milestones and deliverables. This keeps the project on track and allows you to make adjustments if needed. Open communication helps maintain momentum and ensures deadlines are met.

What role does feedback play in successfully hiring a freelance fullstack engineer?

Providing feedback helps the engineer understand what’s working well and what needs improvement. It enables them to adjust their work to better meet your expectations. Constructive feedback leads to a successful and efficient project.
