Reality: Frontend runs on GitHub Pages and the backend spins up on Render & Atlas, but cold starts take ~5 minutes before login/chat/forums respond. Events, profiles, and forums do persist once the free instance wakes up, so I call it a demo rather than a production app.
Practice build that let me explore React forms, profile cards, and an Express API (MongoDB Atlas + Render) with help from tutorials + AI scaffolding.
