Frontend developer with 18 years of experience. I turn complex data into interfaces people can actually use: maps, visualizations, and AI-driven features that combine solid engineering with real design sensibility.

I've built for KLM, Rabobank, and Restor. Currently contracting at Aster on Gnosis, a production AI platform for a Dutch policy consultancy. Outside of client work, I'm building Fahsai, an open-source civic tech app mapping the cross-border origins of Thailand's seasonal PM2.5 crisis.

A lot of my work lands in climate and civic tech. Fahsai and Restor are recent examples.
