About me

drawing

I'm engineer with 5++ years of hands-on experience in different IT areas. I've tried myself in several directions, and after all I've understood that being a DevOps engineer is what I like the most.

A short list of things that I love doing

  • I absolutely love working with Kubernetes. I think it's one of the coolest thing developed in out era. Even if I need to self-host anything I'm always using k8s for that.
  • I like getting rid of manual job, that's why I'm always trying to write scripts and tools for automating everything that can be automated. Mostly, just using bash or wrapping actions in CI pipelines, but if it's something more complicated, I would use Go or Rust already.
  • I always try to use containers when it's possible. The less I need to run 'natively' on my working machine, the better.
  • Administrating linux machines is usually fun for me.
  • Setting up CI/CD and explain developers what's going on there.
  • Resolving incidents and finding the roots of any problem
  • "Everything as code"
