"I had already paid two developers before finding him. First one disappeared after two weeks. Second delivered something that crashed every time more than three people tried to book simultaneously. I was done. I told my wife I was scrapping the whole idea. A friend convinced me to try one more time. He rebuilt the booking system from scratch in Flutter with Supabase handling the backend and authentication. Members book classes, manage their sessions, and get confirmation flows without me touching anything. Six months in, zero crashes. I don't know how he made it look so easy but I'm grateful he did."
