About

Engineering reliable, secure cloud platforms.

I am a platform engineer with around 10 years of experience across software development and cloud infrastructure, including production AWS and Kubernetes platforms.

I work across the full platform lifecycle: infrastructure as code, GitOps delivery, cluster operations, observability, developer enablement, incident response, and security leadership. I am particularly interested in building platforms that are reliable by default and secure without slowing teams down.

As a Kubestronaut, I combine hands-on Kubernetes expertise with cloud architecture, automation, and governance experience. I also enjoy working close to development teams—turning infrastructure complexity into reusable, well-documented platform capabilities.
