Michael Rohrhirsch contributed to two open source projects over a two-month period, focusing on UI design, graphic design, and localization. For the home-assistant/brands repository, he delivered a branding refresh by creating and integrating a new logo and icon for the Kostal Plenticore Modbus integration, enhancing visual consistency within the Home Assistant UI using SVG and JSON assets. In truenas/webui, Michael improved German localization by updating de.json translations, aligning with internationalization best practices to support German-speaking users. His work demonstrated attention to detail in translation management and visual asset integration, though the scope was limited to feature enhancements without bug fixes.
