- Solo dev project written in C++ leveraging Cocos2dx for the UI

- 25,000+ lines of C++20 code

- Created  decoupled Poker engine for Hold’em tournament play from ground up with AI opponents written in pure C++20 leveraging STD library and Boost.

- Advanced probability theory used to implement a hand evaluator and multiple poker bot personas with advanced bots learning from opponent play and applying expected value analysis

- Statistical analysis of hands played and tournament progress

- Catch2 for unit and integration testing to achieve high code coverage metrics and used static analysis tools including CppCheck, Lizard, PMD, and Clang-Tidy

- AI and performance regression suite with a containerized CI build pipeline
