Experience

Piwik PRO (11.2015 - now)

Principal Engineer (10.2021 - now)

Coordination and consultation of solutions for all technical teams in the company (around 40 people in total), being the decisive person in technical disputes, being a primary representative of technical staff when communicating with business, shaping most of the technical cross-team efforts in the company, especially the ones involving day-to-day work: release engineering, CI, CD, coding standards, cross-team cooperation, deployment pipeline, FLOSS policy. Participating in meetings, where broad knowledge of the system is required - high profile clients, due diligence processes. Strictly technical responsibilities include coding (around 30% of time, almost exclusively around deployment automation tooling - go, python, javascript and a lot of DevOps tools) and cross-team code review. The role is internally called “Architect”.

DevOps Team Lead (03.2020 - 06.2022)

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 Q2 2022 12 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.

Participating in on-call rotation for multiple systems.
