ENGINEERING / AI / EVERYDAY LIFE
I build systems that make work clearer.
And look for the extraordinary in the everyday.
构建系统，让工作更清晰。
观察日常，发现不寻常。
Small tools. Real problems.
Built in the open, from hands-on practice.
从真实问题出发，做有用的小工具。
源于实践，开放分享。
See the system.
Find your next move.
看清系统，
再做下一步。
Understand your clusters before the next upgrade, migration, or incident. Resources, relationships, and evidence — in one clear view.
Explore the projectFOLLOW THE RELATIONSHIPS. KEEP THE CONTEXT.
Reusable agent skills for the work worth doing well.
Research, writing, and engineering workflows.
将值得做好的事，沉淀为可复用的 Agent 技能。

Notes on engineering, AI, and the way we work. Written from experience, always open to revision.
All writingFrom cloud operations and platform engineering to teamwork. Sharing what I learn in practice, and learning through conversation.
All talks & videosAn experiment in making a video with an AI avatar, from writing the script to sharing a perspective on AI coding.
I’m Jun Guan, a platform engineer based in Shanghai. I build delivery systems, explore AI in real workflows, and photograph the quiet details of everyday life.
Different practices. The same instinct:
look closely, make connections,
and bring something into focus.
不同的实践，相同的本能：
仔细观察，发现联系，
让模糊的事物逐渐清晰。
