User Case:  Design Native App Interactions and User Interface for Digital Driver’s Licence and Vehicle Registration Document

Creating digital public services is like building a bike for everyone—one that works in a traffic jam, during a rainstorm, and with a flat tire.

Project Overview

I led UX & UI design for secure, native Android and iOS apps used in Germany’s public sector. These apps supported sensitive authentication processes, complied with accessibility (BITV), and required approval across multiple stakeholder groups.

What I Did

• Concepted UX design to align user needs with business goals
• Built and led a lean agile UX UI team 
• Low and high-fidelity prototypes of a digital assistant to simplify complex registration stepsps
• Lean Agile sprints and user testing to deliver practical, adaptable solutions
• Developed personas and localization strategies for multilingual, cross-cultural contexts
• Build a Design system of native UI
• Ensured BITV compliance to make the app accessible and approvable nationwide

Outcome

By combining creative UX thinking with structured design systems and close collaboration with developers, we built public sector apps that were secure, accessible, intuitive, and ready for scale.
