Serhii Zolotov
Cloud Platform Lead / Staff DevOps Engineer
7+ years building and operating cloud platforms across AWS, Azure & GCP. I lead platform practice, automate operational toil, and help teams ship safely at scale through Terraform, CI/CD, GitOps delivery, SRE, observability, security, and AI-assisted engineering. As Cloud Platform Lead at Grid Dynamics, I lead a platform org of 25+ engineers across multiple squads. Open to interesting Staff / Lead / Architect opportunities.

Grid Dynamics
Staff DevOps Engineer · Specialization Lead
Staff engineer on a major retail e-commerce platform — leading platform direction across DevOps, SRE, support, and development teams. Combine hands-on platform engineering with technical leadership, production reliability ownership, cloud cost efficiency, and stakeholder alignment. Built a platform org of 25+ engineers across multiple squads.
- Delivered 15+ platform initiatives end-to-end; authored 3- and 6-month onboarding plans adopted across DevOps squads.
- Migrated production deployments from Spinnaker to ArgoCD; introduced SLOs by metric priority — teams cut incident noise and responded faster.
- Optimized GCP infrastructure in code — right-sized workloads and introduced zero-downtime maintenance where architecture allowed.
- Introduced AI-assisted engineering with GitLab Duo and Vertex AI, routing work by complexity to balance speed, cost, and quality.
- Owned platform security posture: shift-left scanning, secrets management, policy-as-code, and supply-chain hardening.
- Ran guilds, office hours, hiring loops, platform RFCs, runbooks, and a clear definition of done for platform changes.
Senior DevOps Engineer · Specialization Lead
Led multiple teams across DevOps, SRE/NOC, and product-aligned squads. Owned GCP infrastructure with Terraform across Kubernetes, Artifactory, and Spinnaker, and drove delivery and CI/CD modernization across Jenkins, GitLab CI, Helm, and GitOps tooling.
- Participated in on-prem → cloud migration; owned the Spinnaker → ArgoCD transition for production deployments.
- On Jenkins, established the delivery flow teams followed; after migration from self-managed GitLab to GitLab SaaS, introduced shared GitLab CI templates.
- Standardized Terraform-managed GCP infrastructure into a unified platform, and introduced SLO-driven operations, zero-downtime maintenance patterns, and cross-team workflow standards.
DevOps Engineer
Led the NOC team while owning CI/CD pipelines, hardening image build standards, authoring Kubernetes operational runbooks, standing up ELK observability, co-leading migration from on-prem to GKE and VMs, and migrating edge delivery to Akamai with WAF, DNS, and edge security policies.
Sigma Software Group
Strong Junior Systems Engineer
Owned monitoring and incident response across US projects on Azure and AWS.
- Observability with Zabbix, CloudWatch/CloudTrail and Azure Monitor — plus a custom status page for on-prem VMs and Stripe.
- Built and hardened Stripe payment infrastructure: webhook monitoring, integration improvements, and payment-flow security fixes.
- Built Jenkins pipelines, tuned Dockerfiles and OpenVPN networking, and ran the ELK stack.
- On-prem Azure DevOps: Build/Release pipelines, Harbor registry, Ansible roles, HashiCorp Vault and certificate management.
- Delivered AWS infrastructure for a security-focused startup: Jenkins/Amplify deployments, ECR, KMS, OpenVPN, MySQL and CloudWatch.
