I make apps. Currently shipping Check ID, the professional ID scanner for age verification. And Apparent Sudoku, a clean, distraction-free Sudoku game.
October 2026
Check ID for Teams is live — shared setup and staff management for businesses verifying age at the door. Apparent Sudoku 2.4 is almost here, with an all-new design, Game Center challenges, and support for iPhone Duo.

About
I've built for Apple platforms for twenty years — work shipped for NFL, Calm, Chipotle, Food Network — and now my own products. Check ID and Apparent Sudoku are the focus right now, both built privacy-first and bootstrapped. Working on problems I find interesting. Based in San Francisco.
