UI-focused engineer with 4 years building accessible, scalable React/Next apps that improve usability and business impact.
IndiaWhat I'm looking for
I’m a UI-focused engineer with 4 years of experience delivering high-performance, accessible, and SEO-optimized web applications. I build scalable user experiences by combining modern React/Next development with strong product thinking around usability and business impact.
In recent roles, I spearheaded UX discovery for a service desk agent tool by interviewing frontline agents, mapping real-time call workflows, and designing an information-optimized interface that reduced cognitive load and improved call resolution efficiency. I also architected and maintained 15+ reusable design system components across React and Angular, improving development efficiency by 35% while ensuring accessibility compliance (WCAG, ARIA, keyboard navigation). I’ve accelerated delivery cycles by leveraging generative AI to automate test case development, and I’ve supported teams through UI revamps, interactive component work, and knowledge transfer sessions.
