Senior🎓
Top SchoolStefan Koopmanschap is a seasoned PHP-focused software engineer and co-owner of Ingewikkeld with over 25 years working on web applications, certified as both a Zend and Symfony engineer. He blends hands-on development, architecture coaching and legacy-to-modern migrations across clients from public broadcasters to enterprise SaaS, and currently works with TrueFullstaq and Cito while coordinating projects at Concertzender.

Pragmatic and communicative, he excels at turning messy legacy codebases into maintainable, well-documented systems while cultivating developer skill and team ownership.
