August 2025 performance summary: Delivered cross-repo improvements across ecamp and Hitobito apps with a strong focus on business value, reliability, and localization. Key user-facing enhancements include robust PDF generation workflows for ecamp3 (configurable page numbering, TOC page numbers, descriptive PDF names, and progress display) and targeted fixes to PDF rendering quality (emoji handling) and page-number rendering safety. Schedule handling was hardened to reduce duplicates and refresh entries when numbering styles change. English fallback translations were added to improve usability in multilingual deployments and translations were synchronized via Transifex where applicable. Core data and participation workloads were modernized through refactors to a generic participant model across the Hitobito family (youth, pbs, sac_cas, jubile) improving flexibility, export correctness, and test coverage. Several UX/UI quality improvements were completed to increase maintainability and stability (code readability improvements, removal of obsolete references, and improved error handling for undefined values and broken layouts). PR process improvements were introduced to standardize summaries and provide clearer Crowdin PR titles, speeding reviews and deployments.

May 2025 highlights for ecamp/ecamp3: Delivered substantial frontend improvements and reliability across the filtering ecosystem, unifying logic across dashboards and Picasso, adding UI counters, computing filter values, and expanding automated tests for multi-criteria and mobile rendering. Implemented UI/UX and localization improvements by moving content type icons out of translations, added print/ToC filter propagation, and refreshed visuals for mobile UX. Strengthened tooling and quality gates: fixed local dev setup, Caddy deprecation warnings, ESLint configuration, upgraded dependencies (react-pdf to v4), and introduced Cs-fixer with exact version pinning; expanded linting coverage. Fixed critical bugs in invitations flow (claiming open invitations), unique constraint handling, and configuration repair after period deletion, plus scheduling reactivity and ordering fixes. At the UI/UX layer, added a basic filter UI, print filtering, component extraction, and filters applied to ToC, with preloading of activities to accelerate filtering workflows. Deployment and data reliability gains were complemented by helm timeout configurability and visual polish for mobile and print outputs.
