Portrait of Leon Visscher

Hi, I'm Leon. I work at TNO on digital product passports, business wallets and digital twins.

In my own time I build apps under Limosa Software, with a focus on AI recognition in images and audio.

Outside of that I'm into birdwatching and ecology, and especially how AI is used in ecological research.

I write about the things I run into while building.
