Overview
Platform engineering with operational ownership.
I design and operate scalable platforms on Kubernetes, AWS, Infrastructure as Code, and GitOps. The focus is not only individual tools, but how platforms stay secure, observable, maintainable, and operable over time.
In my current role I work on production-grade cloud and platform solutions across Kubernetes, observability, backup & recovery, CI/CD, security, and AI infrastructure — combining hands-on engineering with architecture decisions, automation, and operational ownership.
