Senior🎓
Top SchoolDennis Geus is a pragmatic project manager and full-stack web developer with 12+ years of experience building and optimizing PHP-, Python-, and JavaScript-based web applications and e-commerce platforms.

Process-oriented and self-reliant, Dennis is equally comfortable writing integration code, tuning servers, or translating business needs into reliable technical solutions. Despite a modest GitHub presence, his career reflects steady, practical impact across e-commerce, marketing automation, and enterprise web tooling.
