Why this matters (skills demonstrated)

This project demonstrates an end-to-end sports odds + decisioning workflow:
line ingestion → normalization (decimal odds) → best-price selection → CLV measurement → exportable artifacts.

Built with a clean Streamlit UI and zero-friction templates for fast demos.

Responsible note

This app is educational and workflow-focused. Betting involves risk and variance.
CLV is a process metric (beating the close), not a guarantee of short-term profit.
