+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 on 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
-- One should aim for lesser amount of work with a bigger outcome
 - Unless something is in CI, it doesn't exist
-- Human factor must be avoided when possible
 - 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>
