Build AI with Clarity

Developer Advocate · CNCF Ambassador · AI Native Infrastructure

I work at the intersection of AI Native Infra、cloud-native architecture、open-source ecosystems.

My focus is building clear frameworks、systematic engineering methods、and verifiable RAG/LLM pipelines that help developers adopt modern infrastructure with confidence.
