PROFILE
Xuehan Xiong
Worked on the NVIDIA/NeMo-RL repository to expand and refine evaluation frameworks for reinforcement learning benchmarks. Delivered support for MCQ, math, MMMLU multilingual, and AIME-2025/2026 datasets, enabling broader and more reliable benchmarking coverage. Enhanced the evaluation pipeline by refactoring configuration management and data loading, integrating new datasets, and updating documentation to improve developer experience and onboarding. Addressed bugs in answer parsing and type annotations, ensuring robust and accurate evaluation results. Leveraged Python, YAML, and Markdown to implement features, automate tests, and maintain clear documentation, demonstrating a methodical approach to software development, data engineering, and collaborative contribution workflows.
