About this gig

Is your website throwing errors, loading slowly, or breaking after an update? I fix bugs, errors and issues in WordPress, PHP/Laravel and custom websites fast, and at the root cause, not with temporary patches.

I'm a software engineer with 2+ years building and maintaining production systems, APIs and enterprise web platforms, so I know how to track down what's actually causing the problem.

What I can fix:

  • WordPress errors, white screens and plugin/theme conflicts
  • PHP and Laravel bugs
  • JavaScript and front-end issues
  • API and third-party integration errors
  • Database problems (MySQL / PostgreSQL)
  • Login and authentication issues
  • Performance, speed and optimization problems
  • Server and deployment errors

How it works:

  1. You send me the bug and access (or details to reproduce it).
  2. I investigate and find the real cause.
  3. I fix it, test it, and explain what was wrong.

Why work with me:

  • Root-cause analysis, not quick band-aids
  • Clean, maintainable solutions
  • Clear communication and fast replies
  • Experience with real production and business-critical systems

Not sure if your issue fits? Send me a message before ordering and I'll tell you exactly how I can help.
