What I'm looking for

I’m looking to design modern, user-friendly, responsive UI/UX—partnering with developers to deliver accurate front-end implementation for web and mobile products.

With over 15 years of experience in UI/UX design, I bring a background in information systems and have worked across digital design and front-end development. I’ve collaborated with local and international clients on websites, web apps, and mobile apps, and I’m profjcient in the full design process—from wireframes and concepts to high-fidelity prototypes and delivery.

I’m proud to have been instrumental in developing the fjrst 3D PC game in Sri Lanka, then going on to develop four additional 3D computer games. Most recently, as a Senior UI/UX Designer at DB International Pvt Ltd and Lead Designer at Adup, I’ve designed responsive betting and e-commerce interfaces, created design assets (wireframes, prototypes, and A/B test variations), and worked closely with developers to ensure accurate UI implementation.
