Hochbahn

Jakala asked me to join their team to redesign the hvv switch app. My task was to create various parts of the app with the new corporate identity, ensure seamless integration into the design system and collaborate closely with product and development teams.

My field of work covered pages like Abfahrtsmonitor, Haltestellen- und Liniendetail and Störungsalarm.

The new design components were shared in cocreations and tokenized by the design system.

To ensure proper representation of A11y screens, contrasts, font sizes, focus states and screen reader-compatible elements should be clearly visualized and documented in an understandable way.
