About

I design and implement CI/CD pipelines and infrastructure as code, so build, delivery, and access stop being a team's bottleneck. Experience in R&D teams across fintech and telecom — from migrating Jenkins to GitLab CI, to import-substituting corporate systems and administering infrastructure across 50+ virtual machines.

Open to full-time roles — remote, hybrid, or on-site.

Relocation: Nizhny Novgorod Samara Saint Petersburg business trips — yes
