Hi, I'm

By day I'm a backend engineer on large-scale billing and settlement systems. After hours I'm a product engineer, building things I'd want to use that are worth something to others too.

I love AI. I want it to do away with pointless busywork and be simple enough for anyone to use. And I want it to stay with you over time, like a person would: getting to know you, with real warmth.

I'm drawn to simple, intuitive products and allergic to bloat and ugliness. I play the long game.
