I build production infrastructure and deployment pipelines that teams can operate, scale, and recover with confidence. I’m Anatoliy, a Senior DevOps Engineer specializing in AWS, Kubernetes, Terraform, and CI/CD. I help teams build cloud environments, automate releases, troubleshoot infrastructure problems, and reduce hosting costs. My experience includes production infrastructure for a global SASE platform and a high-scale ad-tech backend, with hands-on responsibility for networking, security, deployment automation, and disaster recovery. RECENT PROJECTS • AWS China disaster recovery — Built independent infrastructure in AWS’s China partition using Terraform and Terragrunt, including VPCs, EKS, IAM roles, private DNS, and GitOps delivery. Established a repeatable rollout pattern across staging and US/EU production pairs. • AWS-to-bare-metal migration — Migrated nine microservices from AWS EKS to servers com Kubernetes while maintaining private Aurora connectivity through a site-to-site VPN. Built a shared CI pipeline that targets either environment through one deployment flag. • GitOps and platform automation — Bootstrapped 31 Argo CD applications, deployed Temporal server and workers, and integrated certificate issuance using HashiCorp Vault and cert-manager. HOW I CAN HELP • AWS infrastructure design, implementation, and disaster recovery • Kubernetes and EKS setup, upgrades, and troubleshooting • Terraform and Terragrunt modules and environment management • CI/CD pipelines with GitHub Actions and Bitbucket Pipelines • Argo CD and GitOps deployment workflows • Private networking, VPNs, DNS, IAM, and secrets management • Cloud migrations and infrastructure cost optimization • Linux administration, Docker, and Ansible automation I focus on repeatable infrastructure, maintainable configuration, and practical documentation. When something fails, I trace the underlying cause—from application and pod networking to host routes and cloud configuration—and document the fix so your team can operate it confidently. You can expect clear communication, early visibility into blockers, and a handover that explains how your infrastructure works. Tell me what you’re building or what’s slowing your team down, and I’ll help define a practical path forward.
