6 months of building BrainTrip solo. Here are the real numbers.
43,000 lines of code. 166 source files. 31 screens. 76 custom components. 22 custom hooks. 5 app versions shipped. All solo.
When you build alone, you wear every hat — developer, designer, marketer, QA, customer support, copywriter. There's no one to hand things off to.
Yesterday I shipped v1.5 — a full performance overhaul. I traced every button tap to find what was causing delay. Parallelized async calls. Built a remote feature flag system so I can kill a broken feature without waiting on an App Store review.
None of that came from a course. It came from users saying "this feels slow" and me refusing to leave it that way.
BrainTrip turns travel into a game — city trivia, AI itineraries, passport stamps, and multiplayer showdowns. Built with React Native, Supabase, and Claude AI.
The app isn't where I want it yet. But progress > perfection. Every time.
