//about

I'm a product-oriented engineer who uses AI to take ideas from 0 to 1 and 1 to 100 — building fast, measuring what matters, and shipping things people actually use.

Currently at Meta driving retention and social connection through Interactive Media on Instagram. Previously co-oped at Curriculum Associates. 4.0 GPA MS CS at Northeastern. I write here about what I'm building and learning along the way.
