Worth the Roast?

Worth the Roast? extracts specialty coffee attributes from a roaster product page, predicts rating and fair price, and compares that estimate with the listed price.

Technical highlights

  • LLM structured extraction from messy product pages into a stable model feature schema.
  • FastAPI inference layer serving local rating and fair-price model artifacts.
  • Currency, bag-size, and roaster-country normalization before prediction.
  • Inspectable provenance through extracted JSON, source snippets, assumptions, and model versions.
  • Render deployment with production configuration separated from browser-facing code.
