Hi, I’m Daniel ‘f0o’ Preussker — a Principal Architect & Staff Engineer based in Stockholm, Sweden.

I spend my time architecting, building, and occasionally breaking things. My focus usually hovers around high-availability distributed systems, hyperscale environments, and critical network infrastructure. Basically, if it involves bridging the gap between kernel-level networking (like BGP or eBPF) and modern cloud-native stacks (Go, Rust, Kubernetes), I’m probably interested.

This site is my public scratchpad. It’s where I dump my research, write about interesting technical rabbit holes, and document the systems I’ve wrestled with over the years.

Feel free to poke around the Posts and Research if you want to see what I’m currently working on. If you’re just looking for the professional timeline, the CV is right there.
