About me

avatar
I'm a Tech leader with strong background in both Software and DevOps engineering. I specialize in cloud platform architecture and release engineering, particularly focusing on Kubernetes-based deployments. I have experience leading engineering teams and coordinating technical initiatives across development and operations. My work spans from hands-on development to designing deployment solutions that serve multiple cloud environments.

DevOps Team Lead (03.2020 - 06.2022) Link to heading

Leading a team of 5 DevOps engineers. Design and development of deployment and configuration management platform based on Kubernetes, terraform and helm, that runs Piwik PRO Analytics Suite (single infrastructure consists of ~400 pods, including applications and stateful components) on public clouds, private clouds, on-premises instances and development environments (as of Q1 2025 ~30 different infrastructures including 5 multi-tenant Azure public clouds, fully automated by terraform). Design of migration system, that allowed migrating the infrastructures from legacy, pre-kubernetes platform. The new platform is used by 4 development and 3 DevOps teams to deliver the software every two weeks for more than 3000 clients. Design and development of release and test automation frameworks for whole platform.

The team had no dedicated manager, so I performed also Engineering Manager role. It included handling cross-team dependencies, resolving potential conflicts within the team, negotiating salary changes with team members, planning self-development activities with team members, running all SCRUM meetings.
