Ka-Ching! was my September 2025 project for BigRed//Hacks: a playful take on productivity where your real Google Calendar becomes the economy of a lightweight tycoon game.
Events are scored by inferred difficulty — sentiment and heuristics over titles and descriptions — and those scores map to different XP rewards so a brutal week actually levels you up in-game.
The stack split cleanly: TypeScript and React on the client, Flask services behind the scenes for persistence, game rules, and the OAuth calendar bridge, with MongoDB as the document store and Google's Gemini API for the NLP-heavy scoring path.
