### About me

I'm a DevOps engineer with 5++ years of hands-on experience with a decent amount of tools. My main focus is Kubernetes and CI/CD, but it absolutely doesn't mean that I would like to avoid tasks in other areas.

As an engineer, I've got some beliefs and I hope that they should be capable of describing me, because that what I'm trying to bring with me:
- One should tend not to repeat oneself
- One should never edit what's constantly generated
- Unless something is in CI, it doesn't exist
- Any routine must be automated, because otherwise it's error-prone

A couple of bigger tasks I've been working on:

- A migration of several MySQL Percona clusters to Kubernetes using the Percona Operator
- An implementation of a downtime-free blue-green deployment for RabbitMQ
- A dynamic "preview" environments deployment using ArgoCD
- A data streaming automation from ~800 Postgres databases with structural changes via Kafka deployed to Kubernetes
- An introduction of versioned Gitlab-CI templates for replacing per-repo pipelines

Also, I'm a maintainer of a kubernetes operator that should help users manage databases via CRDs: <https://github.com/db-operator/db-operator>
