Trail running with dogs

I’m a software engineer shaped by systems work where correctness, performance, and error handling are not just academic concerns.

For over a decade I’ve contributed to the Linux kernel, with long-term work in local file systems. That experience left me with a strong bias: precision matters, and “mostly works” is not good enough. An environment where you must own your mistakes, and where you always need to learn and improve. I loved it.

What I do now

In recent years, my focus has shifted. I still enjoy solving technical challenges, but I am moving away from purely deep technical work toward leading teams, mentoring, and helping others grow.

I’ve come to realize that transferring knowledge to people who share the same goals can have a larger impact than doing the work myself. Today, a lot of my energy goes into building capable teams, setting direction, and creating environments where people can do their best work. I’m actively refining that craft.

At the moment I apply apply my skills to cybersecurity and defensive capabilities at the Czech Ministry of Defence, working in adversarial environments where robustness and correctness are non-negotiable.

What I’m interested in

My technical interests gravitate toward infrastructure you don’t think about until it stops working:

  • Operating systems
  • Storage and file systems
  • Cybersecurity enforcement
  • Distributed systems

I’m especially drawn to systems that are hidden in plain sight-components you interact with constantly without noticing. Working in that space carries a quiet responsibility: contributing to the fabric of modern society without needing to be visible.

Outside of daily work, I:

  • Build small clusters in my homelab to explore distributed systems and ML workloads
  • Study threat hunting, offensive techniques, malware research, and cognitive security
  • Read widely across science, history, and philosophy
  • Collect unfinished pet SW projects
  • Invest in physical training—running, climbing, gym work—because long-term effectiveness depends on both mental and physical resilience

If your work intersects with systems, security, or infrastructure engineering in interesting ways, I’m open to thoughtful collaboration.
