Source Code Optimization

Applications that slow down as data grows, code nobody dares to touch, PHP versions frozen for years: technical debt is paid every day, in time and missed opportunities. I offer analysis and optimization of existing code, with measurable interventions.

What I do

  • Code review: architecture, dependencies, critical points and security.
  • Performance profiling: slow queries, N+1, external calls, missing caches.
  • Targeted refactoring and technical debt reduction, without reckless rewrites.
  • PHP/Symfony version upgrades and dependency updates.
  • Introduction of automated tests and CI/CD where they don’t exist.

Who it’s for

For anyone with an application or ecommerce in production that works “but…”: slow, fragile or impossible to evolve, and who doesn’t want to throw it away and start over.

How I work

I measure before and after every intervention: each optimization must prove its effect with numbers. The path is described on the Method page.

Technologies

PHP 7/8, Symfony, profilers (Blackfire, Xdebug), MySQL/PostgreSQL and query analysis, PHPStan and static analysis tools, PHPUnit, CI/CD.
