Backend software engineer focused on clean architecture, security, and maintainable systems.
I enjoy building reliable services, automating infrastructure, and experimenting with self-hosting and distributed systems.
I run a personal lab where I explore reverse proxies, networking, observability, and cloud-native tooling, most of it documented on my website.

Self-hosting, reverse proxies, networking, and automation are a big part of what I do outside of work.
