About this gig

Is your PHP application slow, throwing errors, or stuck on an old PHP version? I'll fix it properly, not just patch it.


I'm a backend PHP developer with years of production experience at an international fintech company, working daily with Symfony, high-load systems and databases.


What I can do for you:

  • Fix bugs, fatal errors and 500 errors in PHP, Symfony and Laravel
  • Upgrade your code to PHP 8.x and fix deprecated functions
  • Refactor messy or legacy code into clean, maintainable modules
  • Optimize slow SQL queries and database structure (MySQL, PostgreSQL, Doctrine, Eloquent)
  • Fix and improve REST API endpoints and integrations


How I work:

  • Free diagnosis before you order
  • Backup first, all changes tested on a copy, never on your live site
  • A short report of what was wrong and what I changed


Not included: design, WordPress plugin conflicts, server migration.


Please message me before ordering with your PHP version, framework and a description of the issue. I'll confirm the scope and the right package.
