How I work

The best software
feels inevitable.

Fast APIs, security built in from the first commit, and interfaces that turn complicated data into clear decisions. I care about the parts users never see as much as the parts they touch every day.

Selected work

From blockchain investigation platforms to retrieval-augmented AI and secure cloud apps. Built for production, secured by default, tuned for speed.
