It is not launched. It is still one of the most important things I have built. Burnrate forced me to own product, architecture, mobile UX, data modeling, AI behavior, QA, and user feedback at the same time.
The idea: help endurance athletes create race fueling plans based on their event, intensity, gut tolerance, products, and sports nutrition evidence. It was not a tutorial app or a landing page. It became a real full-stack mobile product.
I owned the full system: React Native and Expo, Supabase/Postgres, OpenAI function calling, a RAG pipeline over sports nutrition material, integrations, testing, and the product decisions that determine whether a feature is useful or just technically interesting.
That is the same muscle companies need for AI work: not just prompting, not just strategy, but the ability to connect messy domain logic, product judgment, and technical implementation.
