At DI11 Soft (Pvt) Ltd, I designed user flows and high-fidelity Figma prototypes for enterprise SaaS products, including restaurant POS, inventory, and material production systems. I also created responsive interfaces for complex tables, nested navigation, and real-time dashboards.

I established scalable UI component libraries and design systems guided by HCI principles and accessibility guidelines. My frontend knowledge helped me structure design assets for technical feasibility and smoother developer handoff.

In my portfolio, I designed an enterprise hotel management dashboard that brings fragmented hospitality operations into one B2B SaaS experience. I also worked on LankaLawBot, a generative AI legal assistant dashboard, and EcoChange, a cross-platform e-waste management app, contributing UI/UX design and, for those projects, frontend integration or mobile app development.
