I build systems for the messy real world.
Staff ML Engineer at PayPal. Previously building tools to test and strengthen AI at IBM Research. Still making things from notification datasets, reconstructed rooms and clay.
The story so far
A rough timeline, work and everything else tangled together.
It started with a PhD asking one question: could a notification be considerate?
That curiosity turned into IBM Research — building tools to break AI carefully, before someone else broke it carelessly.
These days it's PayPal, catching fraud at the first mile of a customer's journey.
On the side, the same question keeps following me home — can a room, or a market, tell you something it hasn't said yet?
A camera is never far away either — Cork, Wicklow, Alcalá de Guadaíra, wherever we end up.
Most recently: a hundred small pieces of clay, made with Ana, for our wedding guests.
