Luke Hartman

I'm a generalist software engineer and startup founder. I'm currently automating healthcare clinics in rural America.

Previously, I built Rumbo, a marketplace-style rideshare for LatAm. We scaled to 10k+ users in 2 years with no marketing budget.

I'm very good at TypeScript, NextJS, React, React Native, and Python. I've also done a lot with Postgres, AWS, GCP, supabase, Docker, Go, Rust, C++, Elixir, Bun, and more.

Education

Gonzaga University, 2016-2020

B.S. in Computer Science

Minor in Mathematics
