What I'm looking for

I'm looking to build and operate cloud and Kubernetes platforms, automate infrastructure and delivery workflows, and improve observability for production systems.

I'm building and operating multi-cluster Kubernetes platforms at ChartMogul across AWS EKS and Talos-based bare metal, using ArgoCD and Helm for GitOps delivery.

I've led AWS-to-Hetzner infrastructure migration work, automated cloud and bare-metal provisioning with Terraform, and owned CI/CD workflows with GitHub Actions, AWS CodeBuild, and ArgoCD. I also operate data-intensive systems including PostgreSQL, ClickHouse, Redis, MongoDB, and Kafka.

Across ChartMogul, 888Holdings, Luxoft, Oracle, and Ericsson, I've worked with AWS, OCI, Kubernetes, Linux, networking, observability, and infrastructure automation. I'm CKA and AWS Certified Solutions Architect Associate certified.
