DevOps Engineer

I am a DevOps Engineer with 3 years and 9 months of experience designing, operating, and automating resilient infrastructure. I maintain hybrid Kubernetes environments spanning on-premise infrastructure and Yandex Cloud.

I build CI/CD pipelines with GitLab CI/CD and Helm, automating testing, container image builds, registry publishing, and Kubernetes deployments. My work reduced deployment time from 1.5 hours to 20–30 minutes while supporting frequent production releases.

I use Infrastructure as Code and GitOps practices with Terraform, Ansible, Git, GitLab, and Argo CD. I also automate operational tasks with Bash and Python to make infrastructure management more repeatable and reliable.

I implement observability through Prometheus, Grafana, Alertmanager, Loki, ELK, and Zabbix. These improvements reduced critical-service downtime, shortened incident detection time, and increased service availability from 99.5% to 99.9%.

I administer PostgreSQL, Redis, RabbitMQ, Linux servers, networking, and Kubernetes security controls. My security work includes RBAC, NetworkPolicy, Pod Security Standards, Trivy image scanning, HashiCorp Vault, auditing, and Istio mTLS.
