I'm a Bangkok-based UX Designer turning complex workflows into simple, delightful experiences.
With over 12 years of experience in UX, I’ve helped create user-centered digital products across insurance, fintech, travel, and education.
My focus is on simplifying complex workflows, improving accessibility, and helping businesses design with purpose. Originally from Colombo, Sri Lanka, I’ve spent my career bridging design, data, and development to craft experiences that feel effortless and perform reliably.
When I’m not designing, you’ll probably find me exploring Bangkok’s streets with a camera or experimenting with new DJ mixes at home.
