SRE and platform engineer. Proud dog father. Engineer first, language second: I write patches in whatever the upstream speaks, and these days I spend as much time herding LLMs as typing.
- Open source as practice, not as a slogan
- ARM adoption
- Distributed systems
- GPU and AI infrastructure on Kubernetes
- Self-hosting
- Linux
- Kubernetes
- Go, and whatever else the patch needs
Speaking Russian and English.
SRE at Ænix. Maintainer of Cozystack, a CNCF Sandbox project; among other things I lead its GPU/AI track.

- My own projects, from Kubernetes controllers and Helm charts to MCP servers: awesome.lexfrei.dev.
