Durdans LIMS - Laboratory Information Management System

A Laboratory Information Management System for Durdans Hospital, Sri Lanka, built by a University of Moratuwa team in partnership with IFS - digitising the full clinical-lab pipeline from patient registration to signed report across a multi-branch network, with branch-isolated multi-tenancy, HL7/FHIR/ASTM interoperability, instrument integration, and PDPA compliance, held to a real enterprise standard.

ApexTick - Real-Time Ticket Reservation Platform

A distributed, real-time ticket reservation platform engineered to survive a high-contention flash sale - thousands of people rushing the same seats in seconds, where exactly one buyer must win each seat with zero double-booking. Built as a right-sized Spring Boot microservices system with Keycloak identity, an event-driven backbone, an API gateway, and load-tested proof of correctness.

ICITR 2026 - Conference Website

The official website for the 11th International Conference on Information Technology Research (ICITR 2026) at the University of Moratuwa - a fast, accessible, animated conference site with a live countdown, an interactive eight-track explorer, a hardened contact API, and full SEO. A team project on which I owned the landing page, the For Authors page, the security work, and the SEO.

02About

I'm an undergraduate building thoughtful software with care and craft.

Studying Information Technology at the University of Moratuwa. I obsess over motion, micro-interactions, and making the boring stuff fast. When I'm not coding, I'm reading about typography or shipping side projects.
