About me

I’m Aleks, a CTO and infrastructure engineer working with networking, Kubernetes, observability, security, and open-source software. I’ve been building and operating production systems since 1999.

For contact use al-blogmail@none.at or find me on LinkedIn.

What I write about🔗

Networking, Kubernetes, observability, LLM inference, and open source infrastructure. Most posts are hands-on: setup guides, architecture decisions, and notes from running things in production. For the backstory on why this blog exists, see this post.

Posts are in English. I am a native German speaker, so comments or discussions could also be in German.

This is an infrastructure blog — I do not cover frontend or mobile development.

Passions🔗

I enjoy debugging complex distributed systems and tracking problems down to their actual root cause. Many of the posts on this blog start with a production issue, an unexpected behavior, or a design decision that turned out to be more complicated than it first appeared.

I love learning new things and thinking outside the box — exploring unfamiliar territory and finding unconventional solutions is something I genuinely enjoy.

Security is a recurring theme across my work: from network-level hardening to application security, threat modeling, and secure-by-default infrastructure design.

Philosophy🔗

There is an explanation for everything — we just haven’t found it yet.
