I will fix bugs and performance issues in your java spring boot API

I fix bugs, performance issues, and stability problems in Spring Boot REST APIs used by real production systems. This gig is designed for situations where the backend is slow, unstable, throwing errors, or not behaving as expected.

If your Spring Boot API is broken, underperforming, or difficult to maintain, I help identify the root cause and apply clean, reliable fixes using proper engineering practices.

Common problems I solve:

• API errors and crashes
• Slow response times
• Database performance issues
• Incorrect business logic
• Validation and error-handling problems
• Security or configuration issues

All fixes follow clean architecture principles with a focus on long-term stability, not temporary patches.

This gig is ideal for startups, SaaS products, fintech systems, and business platforms that need their backend to work reliably in production.

Please message me before ordering with a brief description of the issue so I can confirm scope and the right package.
