Building software that scales

I'm a Software Engineer with over 5 years of experience designing and delivering scalable web applications across enterprise environments. Currently at Allianz Insurance Lanka Ltd, I own features end-to-end from UI design through API integration and release across customer, agent, claims, and policy management platforms.

I thrive at the intersection of clean frontend architecture and solid backend engineering. I enjoy leading technical initiatives, improving system performance, and shipping high-quality solutions in collaborative Agile teams.
