FAQs

What should I discuss in the initial meeting with a candidate?

Talk about the project's goals and what you expect to happen. Share the timeline and how you plan to communicate. This is also a great time to check if your working styles match.

How do I create a successful onboarding plan for my hired software engineer?

Give the engineer all the tools and information they need to start working. Introduce them to any team members they might work with. Make sure they know whom to ask if they have questions or need help.

What should I include in the contract for a freelance software engineer?

Make sure the contract includes project details, deadlines, and deliverables. Also, mention payment terms and how you will handle any changes to the project. A good contract protects both you and the engineer.

How do I communicate effectively with a freelance software engineer during the project?

Use regular check-ins to talk about the project's progress and any challenges. Be clear and open about what you need and listen to the engineer's ideas too. Good communication keeps the project on track.

What are some indicators of progress on a software project?

Check if tasks are being completed on time and in the order planned. Confirm that the deliverables match what was agreed upon in the project goals. Regular status updates can help you see how the project is moving along.

How do I ensure the quality of the code produced by a freelance software engineer?

Ask for code reviews and perform tests on the software to make sure it’s working correctly. You can also agree on coding standards before the project starts. This helps maintain a high quality throughout the project.

Your project brief should have all the important details, like project goals, timelines, and special requirements. Tell the engineer what skills and tools they need to use. Clear briefs make sure everyone knows what the final product should look like.
