Rockstar🎓
Top SchoolGert De Pagter is a PHP-focused software engineer with a decade of experience building robust backend systems and a strong emphasis on testing and QA automation. He has contributed to high-profile open-source projects such as infection (PHP mutation testing), PHP-CS-Fixer and symfony/polyfill, helping improve test coverage, reliability, and cross-version compatibility. At companies including YourSurprise and now TactiPlan he combined hands-on development with test-driven practices informed by his academic research internship into testing effects. A blogger and active maintainer-type contributor, he’s comfortable refactoring infrastructure, adding integration and e2e tests, and tightening library documentation and annotations. Based in Middelburg, Netherlands, he brings pragmatic engineering focused on code correctness and maintainability rather than flashy features. Colleagues know him for spotting subtle parsing and test-structure issues that others often miss.
