Projects
-
2026 - 2026 Smart Factory Scheduling — an OpenEnv RL environment
OpenEnv-compliant reinforcement learning environment for industrial job scheduling: assign jobs to machines under stochastic breakdowns and hard deadlines. Packaged as a Docker-based Hugging Face Space.
- Python, reinforcement learning, OpenEnv, Docker
-
2025 - 2025 SlideGen — MCP toolchain
Three Model Context Protocol servers powering a document-to-slides workflow: a webpage scraper/summariser, a PDF analyser, and a PowerPoint generator.
- Python, MCP, uv
-
2023 - present Chess Engine
Chess engine written from scratch in Python (2023), revisited in 2026 to measure and improve it. Raised its strength from about 1060 to about 1650 on Stockfish’s rating scale, measured in 100-game matches per change.
- Validated move generation against published perft counts and python-chess: fixed six rules bugs, then zero mismatches across 573,000 positions.
- Added a UCI interface and a reproducible match harness against Stockfish at fixed ratings, with confidence intervals and every game saved.
- Added and measured each change separately: quiescence search with move ordering (+205), a transposition table (no measurable gain), piece-square evaluation (+335).
- Python, alpha-beta search, UCI, pytest, GitHub Actions
