During the month, contributed to the hitobito/hitobito and hitobito/hitobito_pbs repositories by enhancing multilingual user experiences and improving data model clarity. Focused on refining context boundary handling through updates to kontextabgrenzung.xml, which reduced ambiguity across system contexts. Implemented guest management localization by updating translations in multiple languages and aligning data model fields such as participant_id and person_id for consistency. Addressed localization bugs by correcting IT responsibility translations to match current Transifex strings. Leveraged configuration management, internationalization, and localization skills, working primarily with XML and YAML to automate translation workflows and standardize guest-related features for reliable analytics and UI consistency.
