About

The engineer
behind the system

I'm a software engineer from Colombo, Sri Lanka — I build the invisible infrastructure that keeps financial systems running. At DirectFN, I work on ESB plugins connecting trading platforms and OMS systems with capital markets infrastructure across the Middle East.

My stack goes deep on Java, Spring Boot, and Apache Camel. I've shipped production systems, trained client engineers onsite in Saudi Arabia, and went from intern to Software Engineer in under two years.

I hold an MSc in Computer Science from University of Colombo and a First Class Honours BEng from the University of Westminster — and I'm always building something new.
