Freelance Senior PHP Developer - Symfony & Laravel - Legacy modernisation

available immediately

freelance or permanent - remote or hybrid - on-site within ~1h of Antwerp

Freelance PHP developer with 15+ years of hands-on experience in Symfony, Laravel, and the surrounding ecosystem. I work directly or through intermediaries on enterprise and public-sector projects in Belgium, big or small.

The work I like best is taking over codebases that have outgrown their original design and making them maintainable again. Often that means wrapping old procedural PHP in a modern framework, so the team and I can refactor it step by step instead of betting everything on a rewrite.

I care about the handover as much as the code. Clients have to keep running and maintain what I build after I leave, so I document decisions, keep the stack simple where simple works, and leave tests behind.
