I will debug and fix java spring boot or dotnet backend bugs

I'm a full stack developer with 13+ years of software engineering experience, including work at Microsoft, Safaricom, and I&M Bank. I work across both backend and frontend, using Java, Kotlin, Spring Boot, NET Core/C#, and Angular/React.

If your application has a bug that's blocking your project, whether it's backend or frontend, I can diagnose the root cause quickly and deliver a clean, tested fix. This includes:

• API errors and broken endpoints
• Database connection or query issues
• Authentication and authorization bugs
• Broken UI components or layout issues
• State management bugs
• Frontend to backend integration failures
• Performance bottlenecks on either side

I'll walk you through what caused the issue and how it was fixed so you understand your own codebase better. Send me your error logs, a bug description, or a link to your repo and I'll give you an honest assessment before we start.
