About

8+ years of experience, including hands-on ownership at two early-stage startups where I designed and built backend systems from the ground up. I don't just write code — I make architectural decisions that shape how products scale. I've worked in environments where engineering judgment directly impacts the product roadmap, and I thrive in that kind of ownership culture. Strong foundation in Python and AWS. Comfortable operating with ambiguity, moving fast without breaking things, and raising the bar for the teams around me. Looking to join an early or growth-stage product company where engineering and product work closely together — and where what I build actually matters.
