Who Am I

From production incidents to full-stack deployments — I keep things running.

Having graduated with a BSc (Hons) in Computer Science with First Class Honours, I am currently interning as an Application Support Engineer at Duo Software, I work daily with FreeSWITCH SIP trunking, distributed PostgreSQL clusters (Patroni/ETCD), Redis, HAProxy, and Docker-based deployments. Outside of support work, I've built and shipped full-stack web apps for clients across Sri Lanka and Australia, and researched on-device AI privacy systems for my Computer Science final year project.
