001 / About Me

Who I Am

I am a Software Engineer driven by the challenge of turning complex business requirements into seamless, production-grade applications. With a proven track record of shipping live software across diverse domains such as e-commerce, POS systems, employer portals, and booking platforms, I bridge the gap between robust architectural design and intuitive user experiences. My expertise spans the full stack, from crafting responsive web interfaces with Next.js and TypeScript to developing cross-platform mobile solutions with Flutter and scalable backends using Node.js.

My professional impact is grounded in real-world delivery. During my internship, I contributed to multiple live products where I took ownership of core features such as route protection, complex token refresh flows, and Docker deployments. I thrive in team-based environments, focusing on building secure authentication systems and API integrations that remain stable under the pressure of production traffic.

Currently, I have completed my studies as an ICT undergraduate at the University of Ruhuna and am awaiting graduation. I am finishing my degree with a GPA of 3.63, ranked 2nd in my batch. This academic excellence complements my hands-on experience, allowing me to approach software development with both theoretical rigor and practical efficiency. Whether working on professional contracts or personal projects, I am committed to writing clean, maintainable, and purposeful code that creates genuine value for businesses and end-users alike.
