FAQs

What should I include in my project description to hire a software engineer?

When writing a project description, be clear and detailed. Explain what you need the software engineer to build or fix. Include technical requirements, deadlines, and any tools or languages they should know. The more detailed you are, the easier it will be for freelancers to understand if they are the right match.

How can I assess a software engineer's technical skills on Contra?

Look at their past work and reviews from other clients. Good software engineers often showcase their portfolio projects. You can also ask them to describe how they solved a technical problem in the past. This will help you see if they have the right skills for your project.

What criteria should I use to evaluate a software engineer's experience?

Consider their years of experience and the types of projects they've worked on. Check if they have experience in your specific industry or with the technology you need. You can also look for certifications or special training they might have. This helps ensure they are well-suited for your project needs.

How can I ensure smooth communication with the software engineer I choose?

Set clear expectations from the start about how often and through which channels you will communicate. Decide if you will use emails, calls, or a project management tool. Regular updates are important, so agree on checking in frequently. This helps prevent misunderstandings.

What should I look for in a software engineer's portfolio on Contra?

A good portfolio should show a variety of projects the software engineer has worked on. Look for projects similar to yours to see if their skills match your needs. Pay attention to the complexity of their past work. This can tell you a lot about their ability to handle your project.

How can I set clear deliverables for the software project?

Explain what you expect the final project to look like in detail. Break down the project into smaller tasks or milestones. This makes it easier to track progress over time. Clear deliverables help the software engineer understand exactly what they need to do.

How do I determine a realistic timeline for my project with the software engineer?

Discuss the timeline with the engineer after sharing your project scope. Ask them how long each part of the project will take based on their experience. Be open to their suggestions, as they might know better how much time is needed. A realistic timeline helps keep the project on track.

What steps should I take to onboard a new software engineer?

Start by giving them all the information they need about your company and project. Share any tools they’ll use, and provide access if needed. Explain your processes and team structure. This helps them quickly become a part of your work environment and start the project smoothly.

How can I ensure that the software engineer adheres to quality standards?

Discuss quality standards at the beginning of the project. Specify any coding standards or testing procedures they should follow. Regularly review their work to ensure it meets the agreed standards. Giving feedback along the way helps maintain high-quality outcomes.

What should I look for during a trial period with a freelance software engineer?

During a trial period, assess their communication, efficiency, and how well they meet deadlines. Check the quality of their work and how they solve problems. A trial period helps you see if the engineer is a good fit before fully committing to the project.
