How I Work

I like software that does what it's supposed to do. No over-engineering, no unnecessary abstractions. Clean code, fast queries, and UIs that don't get in the way.

I work on both backend and frontend, so I can take a feature from database schema to the final UI without handoffs. I care about APIs that make sense and deploys that don't turn into incidents.
