I work with clients on freelance software development projects involving website development, application improvements, debugging, testing, and technical troubleshooting. I diagnose frontend and backend issues, repair broken functionality, integrate APIs and databases, improve performance and responsiveness, and help ensure applications are reliable, secure, and user-friendly. I also review existing codebases and implement practical improvements based on each client's requirements.
