## About me
<p align="center">

</p>

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"
