United KingdomWhat I'm looking for
I’m a Platform Engineer / DevOps Engineer focused on designing and automating cloud infrastructure and CI/CD pipelines across AWS and Azure. I build reliable, scalable platform architectures with strong emphasis on infrastructure automation and consistent deployments.
In my recent work as a Cloud DevOps Engineer at EY, I designed and optimized CI/CD pipelines across DEV, QA, UAT and PROD, reducing deployment time by 35–40% through improved pipeline automation. I also automated infrastructure provisioning with Terraform and scripting, improving operational efficiency by ~30%, and integrated Azure services like Key Vault, Blob Storage and Function Apps for secure configuration management.
Previously at KANEFILOUS, I built CI/CD pipelines for containerized microservices, cutting manual deployments by 50%. I automated infrastructure provisioning with Terraform, improved environment consistency, managed Kubernetes workloads with Docker and Kubernetes to reduce downtime by ~20%, and used Helm charts to streamline Kubernetes application releases.
