Jenkins core maintainer and a former board member (Dec 2019 - Dec 2023). Oleg is a community builder, open source and open hardware advocate, and DevRel consultant. He is a CNCF/CDF Ambassador, Testcontainers Champion, and a former CDF TOC chair. Oleg works as a Lead Developer Advocate for Gradle Build Tool, and also does commercial and pro-bono consulting, including Jenkins and CI/CD topics.

Oleg started using Hudson for Hardware/Embedded projects in 2008 and became an active Jenkins contributor in 2012. In 2014, he became a core maintainer. Oleg maintained more than 30 plugins and participated in many projects including JCasC, pluggable storage, and Jenkinsfile Runner. He maintains Jenkinsfile Runner, contributes to several Jenkins SIGs and outreach programs (Google Summer of Code, Hacktoberfest) and organizes Jenkins meetups in Switzerland and online.

In 2022 Oleg took a sabbatical as a core and plugin maintainer due to the war in Ukraine and, hence, changes in the volunteering priorities.
