About this gig

I specialize in debugging Spring Boot applications. Whether your app fails to start, throws HTTP 5xx/4xx errors, or behaves unexpectedly, I identify the root cause and implement a clean, tested fix. My focus is on fast, reliable solutions and clear communication. In my 3+ years of Java experience, I've solved countless backend issues from misconfigured dependencies to authentication problems. Youll get a detailed bug analysis, a working code fix, and brief explanations where needed. 

Why me? I use best practices (unit tests, logging) to ensure stability, and Im responsive: message me anytime to discuss your issue.
