Security Engineer

As a senior security engineer for OVO’s energy technology subsidiary Kaluza, I worked to protect the energy retail platform. My primary focus was the infrastructure security of this cloud-native energy retail platform built on both AWS and GCP; building security tooling and defensive & detective controls for Kubernetes clusters, CI/CD pipelines, managed services. Additionally, I acted as a mentor to junior security engineers on infrastructure security and DevOps; and advised and contributed to platform-level projects from security and compliance perspectives.
