PROFILE
Xuangu-fang
Xuangufang developed advanced experiment scheduling and trace management features for the microsoft/RD-Agent repository, focusing on scalable, diverse, and reliable data science workflows. Leveraging Python and YAML, Xuangufang implemented configurable schedulers—including probabilistic and MCTS-based approaches—enabling nuanced exploration-exploitation strategies and asynchronous multi-trace execution. The work included refactoring core experiment generation logic, integrating LLM-driven prompt engineering, and enhancing configuration management to support dynamic hypothesis discovery. By addressing concurrency, bug fixes, and robust exception handling, Xuangufang improved throughput, reliability, and coverage in automated experimentation. The depth of engineering demonstrated strong algorithm design, reinforcement learning integration, and thoughtful system design for production-scale experimentation.
