At Jam-Soft, I ran production on AWS and Yandex Cloud as the sole DevOps engineer for the first year, supporting 9 backend services and 65 VMs. I owned CI/CD across dev, test, and production, and deployments became ~4× more frequent.
I rebuilt Android CI/CD in GitLab CI, adding merge-request checks and release pipelines for store artifacts. I also set up iOS CI on a Mac mini build host, with builds and tests on every PR and tag-based delivery.
At Bell Integrator, I designed and operated Kubernetes CI/CD infrastructure for a major Russian bank, through which all 11 services were shipped. I also administered around 15 OpenShift environments supporting daily enterprise product releases, integrated monitoring, and maintained runbooks.
