About Me

Engineering Philosophy

I strive for simple but effective user experiences and maintain clear code and performance across the stack. I believe that the best software feels effortless to use and is built on a foundation of straightforward, readable logic.

Life Offline & DIY

DIY-er

I love getting my hands dirty with home renovation. From routing new ethernet cables through multiple rooms and replacing windows, to upgrading bathrooms and kitchen cabinets.

One Man Auto Shop

An enthusiast for working on cars. I enjoy the mechanical complexity (and cost savings) of fixing and maintaining vehicles myself.

Home Automation

I automated my personal Plex media server. It's set up to listen for commands via Signal, automatically handle downloads, torrenting, and content streaming via Plex.
