About this gig

I specialize in fixing broken Java backends, APIs, and production crashes using Spring Boot. If your application is failing in production, has API bugs, or backend issues like crashes, memory leaks, or integration failures, I'll debug and resolve them efficiently.

Services include:

  1. Debugging and fixing Java/Spring Boot backend crashes
  2. API bug fixes and optimizations
  3. Production reliability improvements
  4. Database integrations (e.g., PostgreSQL, MySQL)
  5. Security audits and performance tuning

I work solo, communicate clearly, and deliver clean, maintainable code. You'll get a fully functional fix, not just patches. Message me if unsure about scope.

I’m the founder of Joeksoftwares, where I build and ship my own tools. My main project is Sentinel, a custom anti-cheat system I developed from scratch using C++ and C# to handle low-level security and reverse engineering. ​Beyond that, I’m a full-stack freelancer. I build websites that mimic high-end designs, fix messy backend databases, and integrate payment systems like Paddle and Polar.sh. Basically, if it involves code or hardware, I figure it out and make it work.
