What I'm looking for

I'm interested in platform engineering problems where Kubernetes, cloud infrastructure, and production reliability intersect.

At Accenture, I support a container platform spanning roughly 540 AKS and 250 GKE clusters, with a primary focus on AKS reliability, lifecycle management, security, identity, observability, and production troubleshooting.

I've turned operational issues into repeatable platform controls: I wrote the AKS upgrade SOP used by the team, built reusable Pod Disruption Budget checks, and strengthened Kubernetes change processes with rollback, validation, identity, and disruption reviews. I also traced an OSM/Envoy listener failure after an upgrade and defined a GitOps-based remediation approach, while improving RBAC through dedicated least-privilege workload identities.

Before Kubernetes, I worked across AWS infrastructure, Oracle databases, and WebLogic environments, building experience in cloud networking, high availability, performance troubleshooting, security, and production operations.
