Software Engineer building Cloud Native systems.
I build scalable backend systems, Kubernetes platforms, and developer-focused tools — primarily with Go, Kubernetes, and cloud-native technologies.

Software Engineer II at Circles. Building and operating Go microservices on Kubernetes — currently hardening an API bridging service for a nationwide (22M+ user) migration, with a focus on reliability and observability.
Alongside work: serving as a CNCF Ambassador, leading Kubernetes Sri Lanka and GDG Sri Lanka, and speaking at KubeCon + CloudNativeCon India 2026.
01Selected Projects
Production systems and open-source work across Go, Kubernetes, and the cloud-native ecosystem.
01A live event showcase and voting platform for an AI hackathon — Google auth, role-based access, live Q&A, agenda and a leaderboard, running at low operating cost.
02Contributing to kubernetes-sigs/kro — a CNCF project for Kubernetes resource orchestration that simplifies complex resource management with declarative configurations.
03Root Cause Analysis Agent leveraging LLMs for cloud infrastructure troubleshooting — an autonomous, tool-augmented agent for practical RCA usage.
02Experience
What I've built and owned — from API gateways at nationwide scale to CI/CD platforms.

Sharing cloud-native, Kubernetes, and observability practices on stages from KubeCon to KCD.
From Flaky Builds to Self-Healing Deployments: An OTel-Driven CI/CD Tale
2026KubeCon + CloudNativeCon India 2026
How OpenTelemetry-driven observability turns flaky CI/CD pipelines into self-healing deployments — instrumenting builds and releases to detect, diagnose, and recover from failures.
Episode 71 – Exploring CNCF Project Podman
6 Nov 2025ChatLoopBackOff by CNCF
First-time dive into Podman, the open source container engine redefining how developers build, run, and manage containers. From daemonless architecture to security-first design, see what makes Podman a powerful choice for modern container workflows.
From Blackbox to Glassbox: Teaching Developers Tracing with New Relic
26 Sep 2025KCD Sri Lanka 2025
This topic came straight from our recent work at Circles - building better observability practices and helping developers move from “guessing” to “knowing” with traces.
04Building the Cloud Native Community
My work extends beyond the day job — leading communities, organizing conferences, mentoring open source, and contributing to the ecosystem across Sri Lanka and beyond.
05Writing
Notes on Kubernetes, GitOps, cloud-native tooling, and lessons from building communities.
06Tools of the Trade
Organized by depth, not breadth — the technologies I actually build and operate with.

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.
