About me

English ｜ 中文

As an architect and developer, I have more than ten years of experience in AI platform、large-scale Internet recommendation,and specialized in product design, development, and delivery of AI-related applications such as AI engineering、LLMOPS/MLOPS、recommendation and search systems.

I continuously focus on product and technology in the field of AI engineering.

Highlight

  • I have been engaged in the architectural design and development of AI platforms and AI-driven application systems (such as recommendation/search) for a long time, and have a deep understanding and practical experience in the engineering field of data center AI, LLM AI, and edge AI.
  • I have an experienced product designer, architect and team manager. During my time at 4Paradigm, I led the team in designing and developing core products from scratch, including the machine learning platform(先知/AIOS), the automatic machine learning platform (AutoML/HyperCycle), and marketing enterprise-level customer experience management platform(天枢/CESS).
  • I led the design and development of the AI full-scenario flow orchestration scheduling framework(FlowEngine). This framework is widely used in the decision-making AI projects at 4Paradigm and is now open-sourced and operated by me.
  • I have a comprehensive technology stack, mastering big data、cloud-native、 machine learning mainstream technologies, and have an understanding of trend development.
  • I have a certain influence in the industry, participated in many industry shares and exchanges, co-authored “MLOps Engineering Practice（MLOPS工程实践）” ,currently working on writing “Exploring LLM Application Development（探秘大模型应用开发）”. Additionally, I am the chief editor of “AI Engineering(AI工程化)”. Furthermore, I hold more than 10 patents related to artificial intelligence.
  • I have a certain understanding of enterprise operations, covering the entire process of pre-sales, development, and delivery. I have experience in building a team from scratch and incubating business units.
