About me

I'm a software engineer who enjoys building things that hold up in the real world, not just in demos. Most of my work lives where AI meets production: making language models reliable, measurable and safe enough to trust with real users. I split my time between shipping products for clients, looking at systems from the attacker's side, and building games when I want to tell a story instead of solving a ticket. I learn by building, and there's always something on the workbench.
