I have been writing at xiaoz blog since 2013, sharing practical notes on Linux, Docker, programming, WordPress, and useful tools.
My background spans hosting support, cloud support, Linux operations, and PHP development. I have been working independently since 2022.
I enjoy building reliable web products with PHP, Golang, Python, Vue, and the infrastructure around them, from servers and databases to domains, CDN, and SEO. Most posts here come from real projects and personal experience.
You can get in touch with me through any of the channels below.
