Race strategy for ultra-distance triathlons · iOS and Android · live in both stores
A race-day plan for ultra-distance triathlons such as IRONMAN and IRONMAN 70.3. Tell it your goal and it shows how your swim, bike and run stack up against real past fields on that exact course, then builds a bike power plan to get you there.
- Solo build, from first commit to App Store approval in 17 days.
- Prediction engine built on millions of official IRONMAN race results, with accuracy checked against past races before anything ships.
- Course-aware bike power pacing, saved strategies, sign-in and Stripe subscriptions.
- I own the releases on both stores, CI/CD, crash and usage monitoring, and the production database.

Tell My Mama
Jail-notice service · live beta in Duval County, FL
A fire alarm for getting locked up. Someone booked into jail sends one free request from the jail tablet, and within minutes the people they picked get an email: where they are, what to do in the first 24 hours, and their own instructions.
- Designed around a hard constraint: the only thing a person inside can do is send a request from a jail tablet, so that request is the trigger.
- Members pick up to 3 people. Each one confirms before they get any email, and can stop it any time.
- Built and run solo, including the county guide, consent flow and admin tools.
