Senior UI/UX Designer specializing in research, product strategy, interaction design, accessibility, and scalable design systems.
I'm Dinuka — a Senior UI/UX Designer with 10+ years shipping products across fintech, SaaS, healthcare, and enterprise. I start with the problem, not the pixels: deep research, rapid iteration, and accessibility as a baseline — design that scales through systems and gets out of the user's way.
