Worked on the evcc-io/evcc repository to enhance localization accuracy for German users by addressing numeric value formatting in the user interface. Focused on internationalization and localization best practices, the developer implemented a targeted fix using YAML to ensure that decimal numbers in German strings display a comma as the separator, aligning with German locale conventions. This change reduced the risk of misinterpretation across dashboards, pricing, and session details, and was delivered with a clear, auditable commit history. The work demonstrated careful attention to detail in language-specific formatting and contributed to a more consistent and reliable localized user experience.
