PROFILE

Zachary Fogg

Over four months, contributed to Metta-AI’s metta and mettagrid repositories by building interactive Jupyter notebook widgets, automating installation flows, and optimizing backend performance. Developed features such as a dynamic heatmap widget and Eval Finder for experiment visualization, and enabled distributed training directly from notebooks using Python, TypeScript, and Docker. Improved CI/CD reliability through non-interactive installation automation and centralized environment setup, while addressing critical bugs in training workflows and environment configuration. Enhanced leaderboard evaluation speed in mettagrid by optimizing replay recording logic in C++ and Python, demonstrating a focus on scalable automation, robust DevOps practices, and efficient data-driven experimentation.
