I build the parts of the product people actually touch.
I'm Brennan — a senior frontend engineer in Brooklyn, open to my next role. I've shipped acquisition surfaces at Squarespace, built for Axios Pro and MIT Technology Review at Launch by NTT Data (formerly Postlight), and election-night interactives at PBS NewsHour. I still make side projects when an idea won't leave me alone.

What I'm up to lately
Looking for a senior frontend or full-stack role where I can own high-visibility product surfaces. Rebuilding the Blue Moon registration platform for another race season. Mixing music slower than I'd like. Reading The Soul of a New Machine again — it still holds up.
