I'm Chamod Shehanka, a software engineer from Sri Lanka focused on cloud-native systems: Go, Kubernetes, and the infrastructure that keeps production reliable.
I enjoy building backend services, platforms, and developer tooling that make complex systems easier to operate. That interest in the underlying infrastructure is what pulled me deep into the cloud-native ecosystem, contributing to open source, organizing conferences, and helping grow the community as a CNCF Ambassador.
Outside of engineering, I'm a 2nd Dan black belt in karate and spend my spare time chasing waves along the Sri Lankan coast. 🏄

Have an interesting problem to solve?
Whether it's a cloud-native platform, a backend system, or a talk for your next event, I'd love to hear about it.
