At Qbtech, I worked on digital tools supporting ADHD assessment, helping shape the product experience across iOS and Android. My responsibilities included validating research findings, translating insights into design decisions, and establishing the first design system from scratch to create a consistent foundation for the product. Working closely with developers, I helped define and build the initial design foundation for both mobile apps, turning early concepts into tangible interfaces and reusable components. The work laid the groundwork for future product development, with a focus on usability, consistency and the needs of both users and healthcare professionals.
