Building production-ready web and mobile applications with a focus on clean architecture, performance, and real business impact.
Who I Am
A final-year ICT undergraduate at the University of Ruhuna, graduating with a GPA of 3.54 and ranked 2nd in my batch. I specialize in building production-grade web and mobile applications that solve real business problems.
During my internship I contributed to 8 live products, such as employer portals, e-commerce platforms, POS systems, and studio booking tools, handling route protection, token refresh flows, Firebase integrations, and Docker deployments.
Outside of professional work, I build software across web and mobile with a strong focus on clean, maintainable, purposeful code that creates practical value.
