About Gijs

With over 8 years of experience as a full-stack PHP engineer, I help organizations build, improve, and stabilize SaaS platforms and custom software.

My strength lies in solving complex software problems that development teams often don't have time for. While your team can continue to focus on the roadmap and new features, I'll work in the background to resolve technical bottlenecks and ensure software runs reliably.

This is how I relieve organizations and ensure your development team can keep moving forward.

    Sabbatical
    January 2024 - Today (2 years and 5 months)
    At the end of 2024, I sold my apartment and quit my job at Senet to go on sabbatical for at least a year. Together with my girlfriend Simone and our camper van "Prins Knaus", we traveled through Europe for a year to go sport climbing. In Switzerland, we met our new border collie Nora. It's very refreshing to take a year off after 15 years of hard work to completely reset.
    Enjoying the moment!
