About
Reliability is easy to claim.
Hard to hold under load.
Who I am
Senior Site Reliability Engineer with 5+ years designing cloud-native platforms at Oracle, Zeta and Robert Bosch. I specialise in Kubernetes, GitOps and observability — building systems that are highly available, secure and operationally quiet so engineering teams can ship without fear. The goal is always the same: make reliability invisible.
