About

I'm Leon — a master's student in China studying data systems, data security, and data science. This site is where I keep my public working notes.

What I'm interested in:

• Data systems — databases, storage engines, distributed systems, and the infrastructure that moves data around
• Data security — access control, data governance, and how to build systems that are safe by default
• Open source — I'm learning to contribute to the projects I use, starting with small issues and documentation

I'm writing in English because the community I want to join works in English. If something here is wrong, incomplete, or badly explained — that's a bug, and I'd love to hear about it.

You can reach me onGitHub, or wherever you found a link to this page.
