Message

At SberTech, I orchestrate high-availability Kubernetes clusters and Linux environments, automating deployments with Ansible, Helm, and ArgoCD.

I administer PostgreSQL, Redis, and Apache Kafka clusters, and scale OpenSearch for centralized logging and analytics.

At Sber, I supported Kubernetes and WildFly environments and optimized Jenkins deployment pipelines. I also managed PostgreSQL databases and Apache Kafka clusters while providing L2/L3 support and investigating incidents.

After a career in finance and human resources in the industrial sector, I transitioned to IT through intensive retraining in 2021/2022.
