I am a seasoned Solution Architect and Full Stack Developer with over 19 years of hands-on experience in software design, development, system integration, and enterprise architecture. Based in Sri Lanka, I work with global clients to deliver robust, scalable, and maintainable software solutions across a wide range of industries including logistics, healthcare, travel, education, and e-commerce.
I specialize in writing clean, efficient, and maintainable code following SOLID and GRASP principles, and I bring deep expertise in both back-end API development and modern front-end frameworks.
