Experience
工作经历
Alibaba Group - Tongyi Lab - LLM / AI Infrastructure
AI Infrastructure Engineer - Jan.2023 ~ Now
- Co-designed GPU pooling and request/resource scheduling on 10K-GPU cluster; reduced inference cost by ~90% for mid/long-tail models, ~20% for head models, ~30% overall while meeting SLO. Work published at SOSP 2025.
- Side Project: Built an AI-native stock selection system for A-share market. In the age of AI, a beautiful backtest curve means nothing. What truly matters are two fundamental questions: What edge am I capturing from the market? and How much of that edge can my approach realistically harvest? AI is simply an accelerator for arriving at that understanding.
- Side project: Built ReAct + Self-Evaluation agent loop for game-like programming tasks in a no human-in-the-loop setting (conceptually similar to Ralph Loop).
Alibaba Group - DAMO Academy - Distributed Systems
System Engineer - Jan.2020 ~ Jan.2023
- GraphScope: Designed and implemented the abstraction layer between compute and storage for this large-scale distributed graph system; project ranks #1 on LDBC benchmark.
- Vineyard: Co-founder of this CNCF Sandbox distributed in-memory storage project; led architecture and core module development.
Shanghai Beizhou Investment Management Co., Ltd. - Quantitative Research and Trading
Technical Partner & Co-founder - Feb.2016 ~ Jan.2020
- Led end-to-end design and development of A-share mid/high-frequency quantitative research and trading systems.
阿里巴巴集团 - 通义实验室 - LLM / AI 基础设施
AI 基础设施工程师 - 2023.1 ~ 现在
- 在万卡集群上设计并实现 GPU 池化与请求/资源调度 co-design，在满足 SLO 前提下，中长尾模型推理成本降低约 90%，头部模型约 20%，整体约 30%。相关成果发表于 SOSP 2025。
- Side Project：手搓 A 股 AI 原生选股系统。在AI时代，画出一条漂亮的回测曲线毫无意义。真正重要的是两个根本问题：我在市场中赚的是什么钱？用我的方法，能拿到多大的份额？AI不过是加速你抵达这层认知的工具。
- Side Project：手搓 ReAct + Self-Evaluation Agent 闭环，在无人工介入条件下完成游戏类编程任务（思路类似 Ralph Loop）。
阿里巴巴集团 - 达摩院 - 分布式系统
系统工程师 - 2020.1 ~ 2023.1
- GraphScope：负责超大规模分布式图计算引擎中计算与存储之间的抽象层设计与实现；项目在 LDBC 榜单排名第一。
- Vineyard：联合发起人，CNCF Sandbox 分布式内存缓存项目；主导架构设计与核心模块研发。
上海贝洲投资管理有限公司 - 量化投研与交易
技术合伙人 & 联合创始人 - 2016.2 ~ 2020.1
- 独立负责 A 股中高频量化投研与交易系统的设计与研发。
