AI/ML · WebAn AR whiteboard: notes anchored to real surfaces, shared live between users. Keeping the board stable while the camera moves was the core problem; the first versions only held up in controlled conditions, and it took several rewrites of the homography and optical-flow tracking before it worked anywhere else. FastAPI services sync state over WebSockets, with Firebase behind them, and a Gemini layer answers questions about what's on the board.
