About this gig

Is your Web or mobile application throwing errors, crashing, or just not working the way it should? I can help you find and fix the problem quickly.


With 7+ years of backend experience, I've worked on 40+ production applications and know how to dig into existing codebases without breaking what already works.


What I can help with:

Fixing bugs and errors in Web or mobile applications

Debugging broken API endpoints or integrations

Resolving MySQL query and database issues

Fixing checkout, payment, or form-related errors

Troubleshooting performance or logic issues


Proven track record:

  • Resolved a critical checkout bug that was causing 30% cart abandonment on a live platform
  • Maintained and debugged 100+ production APIs handling 20,000+ daily calls
  • Experience working across e-commerce, marketplace, and SaaS applications


I take a careful, non-invasive approach understanding your code first, then applying targeted fixes rather than risky rewrites.


Send me your issue and I'll take a look.

Backend developer with 7+ years of experience in PHP and Laravel, building scalable systems for real-world traffic. I've architected 100+ REST APIs handling 20,000+ daily calls, integrated Stripe Connect for split payments, and built real-time features (chat, notifications) supporting 5,000+ concurrent users. I built Go Rent It, a rental marketplace, entirely from scratch — including automated Stripe Connect payouts and live messaging. Need a backend built, bugs fixed, or performance improved? I write clean, maintainable code and communicate clearly throughout. Let's discuss your project.
