Introduction

I was born in St. Paul, Minnesota. I spent almost 6 years in the San Francisco Bay Area, but ended up back in Minnesota. I'm currently a Staff (L6) Android Engineer at Block.

I'm 100% self-taught; I started with C++ when I was 13 years old, moved into desktop apps, and then mobile apps when the first Android phones came out. I've also contributed heavily to open source over the years.

Outside of work, I'm into motorcycles & cars, photography, snowboarding, and drums. Music taste ranges from rock, metal & punk to EDM & K-pop. Current loves: 2020 Triumph Street Triple RS 765 🏍️, 2025 Hyundai Ioniq 5 N 🏎️, Canon EOS R6 Mark III 📷.
