Hi, I'm Yunpeng.

I build the platforms that let engineers ship without thinking about the platform.

I'm a Staff Software Engineer at Apple, where I build the infrastructure and AI-powered tooling behind News, Weather, and Stocks.

About me

This site is my workshop: what I'm building, what I'm learning, and the systems I'm trying to make simpler. Ask the assistant anything about my work.

I've spent more than a decade building the platforms other engineers ship on: Kubernetes clusters, CI/CD pipelines, and the internal tools that take the friction out of getting code to production.

At Apple I lead DevOps and infrastructure work for News, Weather, and Stocks. Before that I built next-generation CI infrastructure at Uber's Advanced Technologies Group, and earlier at Apple I took the News automation pipeline from hours to minutes.

These days much of my work is where AI meets infrastructure: retrieval pipelines, LLM assistants, and agentic workflows that let engineers ask for what they need in plain language. I care about reliability, simplicity, and tools people actually enjoy using.

A few facts

  • This site runs on a six-node Raspberry Pi Kubernetes cluster at home, deployed with Argo CD.
  • I started my career in test automation, which is why I still care how things fail.
  • Engineering Systems & Computing graduate of the University of Guelph, Canada.
  • The assistant on this site is one of my own experiments in retrieval and agentic workflows.

How I work

  1. Simplify complex systems

    The best platform is the one nobody has to think about.

  2. Automate the repetitive

    If a task is done twice by hand, it is a candidate for a pipeline.

  3. Own it end to end

    From provisioning to monitoring, the whole path is the product.

  4. AI where it earns its place

    Tools engineers reach for every day, not demos.

What I'm focused on

Building AI-powered DevOps tooling at Apple, supporting News, Weather, and Stocks.

Exploring how LLMs, embeddings, and agentic workflows fit into real infrastructure: not demos, but tools engineers reach for every day.

Iterating on this site as a playground for ideas: chat interfaces, workflow automation, and simpler ways to work with complex systems.
