About

I’m Co-Founder and Founding Engineer at Playful, building AI agents for graphic design. I spend my time on how the agents behave, how people interact with them, and how to make the iOS app fast and responsive.

My background spans computer security, privacy, and human-AI collaboration. I’m interested in the gap between a technically capable system and one that people can understand, trust, and use.

Outside work, I’m learning French and German, exploring cafés, and daydreaming about Europe.

Music

I've been playing the piano for many years, have tried my hand at music production, and am always discovering new music to listen to. Currently, I'm listening to Charlotte de Witte (techno), Nena (Neue Deutsche Welle), Nightwish (symphonic metal), Céline Dion (Adult Contemporary), Ludovico Einaudi (Neo-Classical Piano), and Bon Entendeur (French Electro). Enjoy listening to some of my early efforts at digital music composition and feel free to follow me on Spotify.
