Background

About Me

I'm a full-stack software engineer based in Colombo, Sri Lanka, specialising in Java Spring Boot backends and React / Angular frontends. I build complete, working systems — from database design through to deployed UI.

At Aasa IT Solutions I shipped real enterprise systems: a MOSIP-based Passport Application System handling biometric identity workflows for government use, Inji Certify Verifiable Credential integration using OpenID4VCI, and a pilot government sand mining licence issuance system.

I built production DevOps infrastructure — CI/CD pipelines across Jenkins, GitHub Actions, and ArgoCD with SonarQube quality gates, a Kubernetes observability stack using Prometheus and Grafana, and containerised deployments on AWS EC2 and DigitalOcean.

Currently freelancing — building a live AI-powered e-commerce platform. Actively seeking my next full-time opportunity.
