Over six months, contributed to ZeitOnline/vivi by delivering six features and resolving two bugs, focusing on maintainability and user experience. Work included backend enhancements such as configuration-driven selective publishing and database query optimization using Python and SQL, as well as frontend improvements like modernizing the Rich Text Editor toolbar icons with CSS and PNG assets. Efforts emphasized code refactoring, test stabilization, and repository hygiene, including asset cleanup and documentation reorganization. By upgrading pre-commit hooks and harmonizing code style, ensured consistent code quality and streamlined onboarding. The approach balanced technical debt reduction with practical improvements for editors and downstream systems.
Month: 2025-10 Key accomplishments: - Delivered the Rich Text Editor (RTE) Toolbar Icons Upgrade for ZeitOnline/vivi. Replaced the previous sprite-based icon set with individual PNG assets and updated CSS to reference the new icons, resulting in clearer icons, easier asset maintenance, and a more scalable editor UI. Commit: WCM-1146: Change icons in article RTE (fd4f629f13eab9f17d2cc967965df9c40fd18ab3). Major bugs fixed: - None reported for this period on ZeitOnline/vivi. Overall impact and business value: - Improves editor UX for article authors with clearer, more reliable icons. - Reduces asset management complexity and technical debt by moving away from sprite-based icons to modular PNG assets. - Establishes a maintainable foundation for future RTE icon updates and UI consistency across articles. Technologies/skills demonstrated: - Frontend UI/UX improvements in Rich Text Editor - CSS asset management and migration from sprites to PNGs - Asset referencing and version control traceability (Git commits) - Clear documentation of changes for audits and onboarding

Month 2025-08: Delivered a robust Content Query Sorting fix for ZeitOnline/vivi, introducing a secondary sort on id when print_page is the primary sort and explicit NULL handling. Updated tests to align with new sorting semantics, improving deterministic ordering and reducing edge-case discrepancies in content listings.

June 2025 (ZeitOnline/vivi): Focused maintenance delivering a leaner data model and more reliable tests. Key changes include removing the unused video attribute from the Series data structure and its parsing logic, and stabilizing tests by adding missing serie source entries to sources.txt. These efforts reduce long-term maintenance, decrease data parsing complexity, and reduce CI noise, improving time-to-value for data consumers and downstream systems.

May 2025 (ZeitOnline/vivi): Delivered a configuration-driven selective publishing feature and performed code cleanup to remove dead code, enhancing operator control, reliability, and maintainability. Implemented ignore of specific product IDs during publishing with tests validating that ignored IDs produce an empty payload. Updated tests post-refactor to reflect the new publishing behavior and adjusted expectations. Removed unused encoded attribute from Series across the interface, implementation, and SerieSource, with changelog entry to reduce technical debt. These changes reduce risk of unintended content publication, simplify the codebase, and demonstrate solid testing, refactoring, and documentation discipline.
