Summary
Ruben Van Der Leun is a pragmatic full-stack software engineer with 10 years of experience building web and immersive XR applications across startups and large organizations. He has shipped production systems using Angular, React/Next.js, NestJS, WebRTC and React-Three-Fiber, and led WebXR initiatives integrating A-Frame, Mozilla Hubs and Unity for educational and enterprise projects. Comfortable across backend (Node.js, PHP, .NET) and frontend stacks, Ruben combines feature delivery with refactoring and maintainability—often improving custom platforms used by multiple teams. Currently contributing to Royal Schiphol Group and 360Fabriek while freelancing at Leunix, he blends hands-on engineering with mentorship and cross-disciplinary product work. Outside work he continually experiments with emerging web XR patterns, and once balanced complex real-time video integrations with making meditative VR experiences for wellbeing.
