Modernize Your Legacy PHP Application
A big legacy PHP app that nobody wants to touch, but nobody wants to rewrite either. I modernize it in place: tame the worst code, upgrade dependencies, introduce structure, and migrate to supported, maintainable PHP — without betting the business on a rewrite.
What I Can Help With
Gradually modernize a legacy PHP application.
Typical Problems
Relevant Experience
Modernized the PHP backend for AnalyticsForWebsite — upgraded from PHP 7.x to 8.2, replaced deprecated dependencies, introduced PHPUnit tests for critical paths, and restructured the deployment pipeline. Done incrementally over several weeks.
What Is Included
How It Works
First a technical debt audit, then a prioritized, incremental modernization plan — refactor hot/high-risk areas first, upgrade safely. Fixed-price engagements from €1,500.
Starting from €1,500
Initial modernization engagement (audit + plan + first refactors). Larger scope is estimated after the audit.
Frequently Asked Questions
Rewrite or refactor?
I avoid full rewrites — they almost always fail or take longer than expected. I modernize incrementally so you keep shipping while the code gets better.
What PHP version should I target?
Currently PHP 8.3/8.4. I'll recommend a target that balances your timeline with what removes the most risk.
