About

Oostende, Belgium
7+ years experience

Most of my experience lies in developing web applications, with a primary focus on back-end development and infrastructure. Over time I've cultivated a real enthusiasm for client-side development and interface design — the psychology behind intuitive design, cognitive ease, and user experience as a whole.

I'm passionate about building products and shipping new features, with a strong dedication to design patterns, clean code, and development workflow. I think a lot about how to streamline collaboration, documentation, testing, building, and deployment.

My education in cybersecurity gives me a foundation for designing secure, reliable systems. I embed security principles throughout the development lifecycle rather than bolting them on at the end.
