About Me

I work mostly with Linux servers, DevOps tooling, and networking - setting up infra, automating the boring parts, and self-hosting things I could just as easily pay for.

I like understanding how systems actually work, not just how to use them. Outside of that, I'm usually deep in some rabbit hole - open source, homelab experiments, or a new tool I probably don't need yet.
