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.
