Solo developer in Los Angeles. I ship small, useful web & desktop tools — and I like owning the whole stack, from the first idea to the box it runs on.
Most of what I build scratches a real itch: a tenant checking their rights, a habit I wanted to break, a dashboard I wished existed. I keep scope honest, ship fast, and reach for my own tooling before renting someone else's SaaS.
