What I Work With

A hybrid toolkit grouped by what each tool actually does in the workflow, not by self-rated bars.

Pipeline engineering

CI/CD I actually own end-to-end: Jenkins shared libraries that keep builds consistent across services, plus GitHub Actions for OSS work and personal projects.

JenkinsShared LibrariesGitHub ActionsMulti-module Builds

Infrastructure as Code

Provisioning and evolving infrastructure on vSphere with Terraform, so environments stay reviewable and reproducible, not click-ops on someone's laptop.

Build security & supply chain

Surfacing vulnerable dependencies and protecting client binaries: security wired into the build path, not bolted on after release.

DevOps Intern

Cambio Software

Current role

June 2025 - PresentSri Lanka

Working in Cambio's DevOps team, building, hardening, and debugging the pipelines that ship real production software.

Designed and maintained CI/CD pipelines in Jenkins, and contributed to the team's shared library so builds stay consistent across services.
Provisioned and upgraded infrastructure on vSphere with Terraform, treating environments as code rather than tickets, and evolving the IaC as the platform grew.
Handled Java/Maven and Gradle build tooling across multi-module projects, including Java version migrations and debugging distributed build-agent failures.
Integrated Dependency-Track with CycloneDX SBOM generation into the build path to surface vulnerable transitive dependencies before they leave the pipeline.
Implemented ProGuard-based obfuscation for client-shipped JARs, protecting IP without breaking build reproducibility.
Built a checksum-based dependency identification system for binary-level artifact tracking, catching a class of problems that version strings alone can't.
Operated day-to-day in a Windows-based DevOps environment (PowerShell, Windows agents, real-world constraints) while supporting engineering teams when their pipelines broke.

Production CI/CD Pipeline for a Java Web App

An end-to-end delivery pipeline that takes a Git commit all the way to a running pod on Amazon EKS, with automated testing, code quality gates, image scanning, and GitOps-driven deployment.
