Hi, I am Zygmunt.
This is my developer home. I build and publish software for Linux, packaged as snaps.
I am Zygmunt Krynicki, a software engineer based in Warsaw, Poland. For more than ten years, I have worked on snapd and snap packaging. At Canonical, I work on the snap sandbox and on packaging snapd for Linux distributions. I studied computer engineering at the Polish-Japanese Academy of Information Technology, where I specialised in parallel programming.
Much of my career has gone into automated and hardware testing, including the Checkbox and LAVA testing frameworks, and into the packaging and security tooling around snaps. My projects here reflect that: infrastructure for testing software on many systems, small utilities for inspecting Linux internals, and a growing set of tools for working with AI agents.
Most of my code lives on GitLab, and the applications I have published as snaps are listed on the Applications page.
