Alexander Turek is a Staff Engineer based in Düsseldorf with 24 years of experience building and hardening PHP systems, currently shaping platform engineering at easybill after senior roles including Director of Software Development and a decade as a freelance consultant. A long-time Symfony and Doctrine core team contributor, he focuses on modernizing legacy codebases—adding strict typing, improving tests, and smoothing deprecated APIs—so code "aged like a good whisky" stays maintainable. He pairs deep framework internals and security experience (notably across Symfony Security, HttpKernel and Console) with a pragmatic eye for testing and CI, having improved PHPUnit tooling and Composer behavior. Comfortable across backend, tooling and documentation, he quietly bridges fast iteration and long-term stability, often preferring surgical refactors over rewrites. Trained in computer science at KIT, he brings a rare combination of institutional memory and continual modernization to large open-source ecosystems.
