Site — loads, but the backend is retired
Source

A full coaching platform for flag football. Coaches build playbooks with visual play diagrams, manage rosters across seasons, plan practices with linked drills, run game day from wristband-mapped play sheets, and track play-by-play results. Version 2 was a ground-up rebuild around mobile-first sideline workflows.

A 27-table relational schema: teams, players, seasons, playbooks, formations, games, chat, announcements
Visual play diagramming with formation data stored as JSON
Game plans with wristband color and number mapping for sideline use
Shared access tokens with scoped permissions for parents and assistant coaches
V2 replaced a no-build-step React prototype with a proper Next.js and Supabase architecture

The MyFlagCoach sign-in screen. — Sign-in. The screens past this point needed a live backend to capture, and it has since been retired.
