Four apps and counting. Each one made for someone specific.
A private relationship dashboard. One household. Eight years of communication, music, and shared life, collapsed into the screens that two specific people open every morning.
Forensic-grade race timing for 1:64 scale Hot Wheels tracks. ESP32-S3 firmware, sub-millisecond timing, audio cues, and a physics teaching mode. Originally built for a sixth-grade science fair.
League management for traveling women's golf leagues. Schedules, scoring, member directory, course rotation across thirty-nine Front Range courses. Built to retire a Google Sheet that did too much for too long.
Automated grade verification and homework accountability for parents. Pulls assignment data, detects grading errors, tracks submissions, and delivers daily reports to the whole family.
No advertising. No tracking SDKs. No data brokers. No "growth." Each app is built for the people who use it, and that's the user count we optimize for.
