About this gig

Is your application crashing, slow, or showing unexpected errors?


Stop losing users due to technical glitches. I am a Senior Software Engineer with 4.5 years of experience in debugging complex systems. I specialize in finding the "needle in the haystack" and optimizing code for maximum performance.


What I Can Fix for You:

  • Laravel/PHP: Fixing Eloquent queries, Middleware, and Auth issues.
  • Node.js/NestJS: Resolving asynchronous loops, memory leaks, and API failures.
  • Database: Optimizing slow MySQL queries, indexing, and Sharding issues.
  • API Issues: Troubleshooting REST/SOAP integrations (like Duffel or Stripe).
  • Performance: Implementing Redis caching and code refactoring.


Why Hire Me?

I dont just "patch" the code; I find the root cause to ensure the bug never returns. My experience with massive systems like OmniShard-1B means I understand how to handle performance at scale.


Contact me now with your error log, and let's get it fixed today!
