FAQs

Look for someone skilled in Java programming. They should know frameworks like Spring or Hibernate. Experience with databases and APIs is a bonus. Check if they can manage the full software development lifecycle. This means they can plan, test, and launch your project smoothly.
Start with a clear project brief. Include goals, deliverables, and timelines. Discuss the project's scope in detail. Ask for examples of similar projects they've done. This helps ensure they know what you're looking for.
Deliverables can vary based on the project. You might get a complete software application. Some projects need APIs or system integrations. Confirm all deliverables with the freelancer before starting. This avoids surprises later on.
Review their past projects and client testimonials. See if they faced challenges and how they solved them. Problem-solving is key in Java development. A good freelancer shares how they tackle issues. Ask them to explain their problem-solving process.
Look for variety in their work. Check if they've done desktop apps, web services, or enterprise solutions. A diverse portfolio shows experience. Make sure they use LSI keywords for relevant skills. This includes things like 'JavaEE', 'Spring', or 'Maven'.
Discuss timelines early with the Java expert. They know how long each task should take. Set milestones for parts of the project. This helps track progress and adjust schedules. Use Contra's tools to monitor this during the project.
Set up regular check-ins from the start. Use Contra's messaging tools for updates. Be clear about your preferred communication style. Encourage them to ask questions if unsure. This keeps the project running smoothly.
Ask for coding samples or a demo of past work. Review the code for clarity and efficiency. Check if it's well-commented and organized. You can also give them a small, relevant task to complete. This shows their coding skills firsthand.
