Built and maintain a Python CLI tool that keeps shared GPUs active with lightweight keep-alive workloads, plus a matching Python API.

Built LoRA‑fine‑tuned models with pseudo‑labeling and ensembles; earned Silver Medal (39/1,849 teams).

Lightweight Monte‑Carlo Tree Search pipeline for LLM agents; supports OpenAI/DeepSeek APIs with optimized rollout policy.

2.5D narrative adventure; produced teaser and achieved charity certification from Beijing New Sunshine Charity Foundation.

Contributed SDK improvements for model naming compatibility, log tooling, and message/image serialization in Responses workflows.

Fixed rope scaling override order so Hugging Face config conversions stay correct after legacy overrides.

Extended-context fixes and truncation improvements for RL pipelines (YaRN), with tests across rollout workers.

Long-context evaluation and analysis: reproducible data synthesis, 128k LLaMA3-7B single‑GPU inference, and Phi3 retrieval-head support.
