Hi, I'm Yiying 👋

I'm a software engineer based in London, working on production systems, AI evaluation, developer tooling, and cloud infrastructure.

I enjoy building the less visible but essential parts of software — the pipelines, observability, automation, and platform capabilities that help engineers ship and operate reliable systems.

My current technical interests include:

  • Production AI and LLM evaluation
  • Observable asynchronous workflows
  • Developer tooling and internal platforms
  • Kubernetes and event-driven systems

Based in London · CKA-certified · Background in Economics and NLP data quality
