Hi, I'm Andrew. I work at the intersection of engineering and customers.

Partner Engineer at Uber with 9+ years solving technical problems for external clients. I ship real-world solutions and develop full-stack consumer apps.

👋 About me

I live at the crossroads of technical and customer-facing.

As a Partner Engineer, my favorite work happens in the space between deep technical problems and the people on the other side of them. I speak fluent engineer and fluent customer, and I love translating between the two: scoping the real problem, building the solution, and making sure it actually lands.

That same instinct carries into my own projects. I build consumer apps end-to-end with React, React Native, Swift, and a lot of Supabase, then ship them to real users and learn from how they use them. I hold a M.S. in Computer Science from Pace University.

Technical x Customer-facing

I live at the crossroads of engineering and the people who use it, turning real customer problems into working solutions.

🚀

0 to 1

I take ideas from a blank repo to a shipped product, comfortable owning the whole path from spec to launch.

🧩

Full-stack & AI

Web, mobile, backend, and AI-powered tooling, I reach for whatever the problem actually needs.
