What I learned
This was the project where Supabase clicked for me. Auth, postgres, real-time, and row-level security all in one place — once you stop fighting it, you can ship a real multi-user app in a weekend instead of a quarter. The other lesson: building for yourself first is the fastest path to a useful product, because the feedback loop is instant.
What I did
- Designed and built a full-stack habit tracker — log exercise days and drink days against a calendar.
- Wired Supabase auth for sign-up, login, and per-user data isolation via row-level security.
- Used real-time subscriptions to keep multi-device state in sync.
- Built the frontend in React + Vite with a calendar UI that visualizes patterns at a glance.
What I shipped
A live multi-user habit tracker at https://fitquench.netlify.app with a small but real user base — the app I actually use to replace the paper calendar that used to live on my fridge.
