About Me

Full-stack engineer based in NYC

I build products from idea to deployment: fast, clean, and with real attention to UX. I'm most at home in TypeScript and React on the frontend, Python and Django on the backend, and AWS when it's time to ship.

I got my start through General Assembly's software engineering immersive and have been heads-down building ever since, working across startups, agencies, and enterprise clients like Bloomberg.

Before code, I earned a DMA in musical performance and played with orchestras. These days I channel that same obsessive attention to detail into software, and still find time for running and chess.
