What I'm looking for

I’m looking for a DevOps/Platform role where I can deliver secure, observable, fault-tolerant infrastructure through automation and strong change control—prioritizing measurable operational reliability, cost/resource optimization, and smooth production support.

DevOps Engineer with more than 5 years of experience in high-load environments. I design and implement end-to-end infrastructure and platform solutions, from requirements analysis and risk assessment to automation and production support. I build reliable engineering processes around delivery by standardizing workflows and strengthening change control, security, observability, fault tolerance, and resource/cost optimization.

In recent work, I improved CI/CD security by implementing artifact signing (Vault Transit, Cosign) and enforcing signed, policy-compliant deployments with admission-layer verification. I also standardized delivery reliability—unifying SemVer library versioning (reducing support requests to ~5 tickets/month), standardizing Flyway database migrations (cutting pre-production migration errors to ~2%), and increasing Terraform reusability via Terragrunt (100% code reuse, ~90% fewer manual changes). I’ve delivered zero-worker-downtime Kubernetes cluster migrations (master failover in 27.6 seconds) and optimized cloud cost with EKS autoscaling and Karpenter (14.8% cost reduction).
