Summary
👤
Senior🎓
Top SchoolSebastian Hagens is a creative full-stack webdeveloper and tech consultant with 12+ years of experience building pragmatic websites and webapps for entrepreneurs and smaller organizations. Rooted in PHP and JavaScript, he frequently uses Drupal and Vue/Nuxt while experimenting with Symfony, Docker, TailwindCSS and niche tech like Bitcoin Lightning and Nostr. He runs his own consultancy Sebastix, contributes to the FOSS nostr-php library and researches long-term contributions to the Nostr ecosystem—bringing open-source sensibilities to client work. Comfortable from interaction design and wireframing in PenPot to backend automation with GitLab and shell scripts, he turns complex digital problems into simple, maintainable solutions. Based in Oudenbosch, Netherlands, he pairs a hands-on maker’s mentality (making things on the web since age 12) with clear, practical technical advice and second-opinion consulting.
