About

I'm a senior fullstack engineer with deep expertise in building scalable, modern web applications. With hands-on experience across React, Node.js, TypeScript, Remix, PostgreSQL, Redis, and AWS, I've delivered production systems at companies like Routescanner, Sunweb Group, bol.com, and Rabobank.

I specialize in end-to-end application development -from designing robust APIs and data models to building responsive, performant frontends. My work at Routescanner on GIS systems with Mapbox and real-time maritime data processing demonstrates my ability to tackle complex technical challenges.

I care deeply about code quality, developer experience, and sustainable engineering practices. Whether architecting a new platform, optimizing build pipelines, or mentoring developers -I bring technical depth, pragmatism, and a strong bias for shipping.
