What I'm looking for

I’m looking for a remote-friendly role where I can build and automate multi-cloud infrastructure, lead Kubernetes/IaC delivery, and strengthen security and observability. I thrive in teams that value DevOps culture, shift-left practices, and real ownership.

I’m a Senior Cloud & DevOps Engineer with 8+ years designing, automating, and operating production infrastructure across AWS and Oracle Cloud Infrastructure (OCI). I deliver large-scale, mission-critical environments for enterprise teams in telecom, fintech, and industrial settings.

I’m fluent in Kubernetes (EKS/OKE) and IaC, using Terraform and GitOps workflows to standardize provisioning and accelerate delivery. In CI/CD, I build and maintain pipelines with GitLab CI, GitHub Actions, Jenkins, and ArgoCD, while focusing on observability with Datadog, Prometheus, and Grafana to improve incident detection and MTTR.

Across accounts, I also lead multi-cloud governance, security hardening, and access/secrets management—bridging AWS best practices into OCI workloads. I’ve collaborated directly with Oracle engineering teams on pre-GA services and coached developers on DevOps culture, shift-left security, and platform self-service patterns.
