I'm a full-stack engineer — most recently I was at Headspace on a growth flavored team. Before that, I spent ~4 years at Tessitura building an order-processing app in Angular/RxJS.

On the side I'm working on a Cosmos Institute-funded project applying fuzzing, mutation testing, and formal methods to AI-generated code, so a human can actually judge whether it's right.

Thanks!
