About

I build and ship products end-to-end —
mobile, web, and the backend underneath

Hi, I'm Nicole, a full-stack engineer in New York who builds entire products across mobile, web, and backend, because I like being able to solve a problem wherever it lives in the stack. I love learning about the world, and engineering turns out to be one of the best ways I've found to do that, since it keeps pulling me into corners of life I'd maybe never have seen otherwise. Away from the screen I'm always chasing some new hobby into the ground. Right now it's archery! I care about the parts that are easy to skip: accessibility, UX that actually works, obsessive attention to detail, and keeping scope honest. I came up through QA, so I catch the broken edges early. I do my best work with curious people who treat growth as part of the job. If I don't know how to do something yet, that's usually why I want to.
