Kubernetes on Yandex Cloud. Migrating services to K8s, upgrading infrastructure. GitLab CI/CD with Helm. Cross-team collaboration.

Building and optimizing cloud infrastructure for a startup environment from the ground up. My focus is on creating a seamless, automated ecosystem that balances performance with elegance. - Cloud & IaC: Designed and manage full-stack infrastructure on Yandex Cloud (YC) using Terraform, ensuring infrastructure-as-code principles are applied consistently for reproducibility and version control. - Kubernetes & Networking: Deployed and maintain production-grade Kubernetes clusters, configuring Load Balancers, ingress controllers, and network policies to support scalable microservices architecture. - CI/CD & Self-Hosted Tools: Implemented self-hosted GitLab CE with custom CI/CD pipelines, enabling automated testing, container builds, and zero-downtime deployments. Integrated container registry and artifact management. - Observability & Resilience: Established end-to-end monitoring using Sentry (application errors) and Grafana (infrastructure metrics). Centralized logging with ELK stack for faster troubleshooting. Secured data via automated S3 backups and versioning. - Optimization & Automation: Managed CDN configurations for global content delivery, optimized DNS routing (Cloud DNS), and developed Python services to automate routine tasks and internal tooling.

Driving DevOps transformation for a distributed aero-tech team, focusing on automation, reliability, and developer enablement. - Infrastructure Modernization: Migrated legacy XEN/libvirt virtual machines to containerized environments (Docker Swarm/Kubernetes), improving resource utilization by 40%. Managed 500+ CentOS VMs with NGINX load balancing. - CI/CD Leadership: Built GitLab CI/CD pipelines from scratch, reducing deployment time from hours to minutes. Automated testing, security scans, and releases for Java/Python/PHP/.NET/C++ apps. - Monitoring as Culture: Unified monitoring using Prometheus (metrics), Grafana (dashboards) and Zabbix . Created custom dashboards for app performance, DB health (MySQL/PostgreSQL), and infrastructure costs. - Automation First: Eliminated manual interventions via Ansible playbooks for configuration management and Bash/Python/JS scripts (e.g., log rotation, certificate renewals, DB migrations). - Developer Partnership: Collaborated daily with dev teams to optimize environments, debug application issues (Java/Python/C#), implement feature flags, and design scalable logging solutions. Supported Blue/Green deployments.
