What I'm looking for

I’m looking to build secure, scalable cloud-native platforms where I can lead DevSecOps, Kubernetes operations, and automated CI/CD—using observability and GitOps for reliable releases, measurable uptime, and continuous compliance improvements.

I’m a Senior DevOps and Cloud Infrastructure Engineer with 9+ years of experience designing, automating, and managing scalable cloud environments across AWS, Microsoft Azure (including Azure Government Cloud/GCC High), and Google Cloud Platform (GCP).

I specialize in Kubernetes (EKS, AKS, GKE) and Infrastructure as Code (Terraform, CloudFormation, Bicep/ARM). I’ve improved provisioning speed, scalability, and resilience by building reusable Terraform modules and modernizing platforms from monolithic architectures to cloud-native Kubernetes workloads.

In every role, I focus on DevSecOps and compliance—implementing security controls like SAST, DAST, secrets management, and vulnerability scanning. I’ve supported FedRAMP, NIST 800-171, SOC2, and CMMC aligned environments, including Azure Government and AWS GovCloud.

I also build for reliability and visibility, implementing observability with Prometheus, Grafana, ELK Stack, Datadog, CloudWatch, and Azure Monitor. From centralized monitoring to GitOps-based deployment workflows, I aim to deliver secure, highly available systems with consistent releases and measurable uptime.
