Building systems.
Thinking about security.

I build data platforms and backend systems, then stay curious about the problems underneath them.

02 / Now

Still curious.

I’m broadly interested in security.

herdr-lazy is complete for now and maintained on an as-needed basis. I revisit it when Herdr changes or a bug needs attention.

My TiDB contribution was a first step into open source, not an ongoing project.
