About

I'm a Product Engineer and CS student at UW-Madison ('26), building full-stack mobile and web applications.

Currently founding LOJIK Labs, a product studio focused on shipping high-utility SaaS products with production-grade engineering practices.

When I'm not coding, I'm producing music in Logic Pro X, playing golf, or thinking about systems.

Let's Connect

Open to founding engineer roles and interesting projects. Currently based in Madison, WI.
