About this gig

 Is your code broken? API failing? Database crashing? DON'T PANIC.

When your business operations stop because of a technical error, you don't need a junior developer learning on the jobyou need a system architect who can diagnose and solve the problem immediately.

I specialize in diving into existing codebases, finding the root cause of the bug, and fixing it fast. Whether a previous freelancer abandoned your project, a third-party API updated and broke your script, or your database is returning errors, I am here to rescue your system.

What I can fix for you TODAY:

  • Python Errors: Syntax errors, infinite loops, logic bugs, and broken automation scripts.
  • API & Integrations: Fixing broken endpoints, JSON parsing errors, Webhooks, and authentication (OAuth/Tokens) issues.
  • Database Issues: Fixing broken PostgreSQL queries, migration errors, or connection timeouts.
  • Cloud & Server: Fixing deployment errors in multi-tenant architectures and cloud environments.

Why hire me? I build robust commercial-grade POS systems and industrial monitoring architectures. I know how production environments work, and I treat your emergency with the urgency it deserves.
