Tournament Math — Reusable Domain Logic & Testing

Tournament Math is an open-source library from my product engineering work through TourneyTek, Inc. It separates reusable poker tournament logic from the user interface: ICM equity, payout curves, table balancing, close-table seat planning and stack pressure.

Pure functions, zero runtime dependencies and typed ESM/CommonJS exports make the logic reusable and independently testable. This work demonstrates domain modelling, API design and maintainable library engineering.
