Lego × IA
Google showed off an AI that judges LEGO builds at its Cloud Summit, and we rebuilt it in three days for a contest between two directors. As first-year Epitech students with no prior experience, at a time when AI API keys were hard to get and most Google AI services weren't enabled in La Réunion, we found our way through Vertex AI.

Context
After Google ran a LEGO challenge judged by AI at the Google Cloud Summit Paris 2025, the Réunion campus wanted a rematch between its director and Epitech's managing director. No public tool existed, so we built one, with no prior web or API experience.
What was built
- Real-time game flow: players join by code from their phones, state synced through Supabase Realtime
- Node/Express backend that sends each photo to Gemini with a 100-point scoring rubric
- Replaced Firebase and Gemini API features unavailable in La Réunion with Supabase and Google Cloud
- Ran the live contest between the two directors
