I take products from zero to one, and own every layer.

Infrastructure, backend, UI, and UX—I own all of it. I was the sole engineer behind TravelArrow, which grew to 250K users and $1.5M ARR. At Roger (YC S24), I designed the systems behind 5,000+ jobs a minute and 100K+ emails a day while leading six engineers.
