Operator, not influencer.

I'm echocc00, a security and network engineer based in Shanghai. I spent nine years in cloud security & network engineering and I'm CCIE-certified.

The work on this site is what I run, not what I blog about: code I deploy, alerts I page on, changes I push through review.

In 2024 I started turning one-off internal tools into six Apache-2.0 open-source products.
