Quality Engineering, Test Automation & DevOps

Quality Engineering, Test Automation & DevOps Consultant

A hands-on Quality Engineering, Test Automation, and DevOps consultant who works across the delivery lifecycle: from test strategy and automated API/UI testing to CI/CD, Kubernetes, GitOps, and secure platform engineering. I help teams build quality into their pipelines, infrastructure, and release processes across AWS, GCP, and on-prem environments.

I combine QA leadership and test-management expertise with practical implementation skills in Python, Bash, GitLab CI, Jenkins, ArgoCD, Docker, Helm, Terraform, Vault, and cloud-native tooling. This enables me to bridge development, operations, security, and quality teams while improving delivery speed, reliability, compliance, and observability.
