As a Senior User Interface Designer at Viessmann, within a large team of developers, I co-designed ViCare the main B2C app. As result the app ratings improved from 2.7 to 4.6 stars.

Defined the handover process and tooling, migrated tool from SKetch to Figma and built a design system standardizing +100 components to improve consistency and speed up development.

In the examples below my work on the HEMS (Home Energy Management System) feature of the app, this included management of inverted and battery systems, EV charger and Dynamic Tariffs.
