Grinta

Grinta is a web platform for football coaches and clubs that I'm building with Elio, a friend. It centralizes everything a staff handles day to day: season planning (year, month, week and day views), an exercise library, session preparation, team and player management, call-ups and progression tracking. A parents' space shows call-up details and schedules. The idea behind it: give training clubs "one identity, one method" that survives coaching changes.

On the technical side: Next.js (App Router), Supabase with Row Level Security to isolate each coach's data, next-intl for French and English, and FullCalendar for the planner. The PostgreSQL schema is designed to be additive, so a paid tier with exercise sharing can be added without touching the rest of the app. Grinta is free for independent coaches, with club pricing on request.
