global talent verified by Toptal

Generalist engineer.Deep systems bias.

I'm an engineer who can move across the stack: application code, cloud architecture, DevOps pipelines, platform automation, security controls, observability, and production operations. My strongest depth is cloud-native infrastructure, but I do not stop there.

Today I work as a Senior Cloud Infrastructure Engineer at DP World, operating Kubernetes and platform systems for enterprise logistics. Earlier roles had me building applications, migration tooling, self-service platforms, CI/CD systems, security pipelines, and cloud foundations across AWS, Azure, GCP, OCI, and vSphere.
