Serdar Bahar contributed to the bounswe/bounswe2025group5 repository by building and refining mobile features that enhance user engagement, accessibility, and localization. Over five months, Serdar delivered backend-integrated content discovery, robust authentication, and dynamic post creation using React Native, TypeScript, and Spring Boot. He implemented cross-platform image uploads, centralized internationalization with English and Turkish support, and improved accessibility through VoiceOver and dynamic labels. Serdar expanded test coverage with Jest and Testing Library, strengthened password validation, and integrated reporting workflows. His work addressed both frontend and backend concerns, resulting in a more reliable, maintainable, and globally accessible mobile application experience.

Dec 1, 2025December 2025 — Monthly summary for bounswe/bounswe2025group5 Key features delivered: - Notifications stability and UI improvements: fixed token refresh race causing 403 errors; ensured notification badge updates on explore screen focus; center-aligned badge text; restored username parameter for notification thumbnails; added comment previews in comment notifications. - Mobile accessibility enhancements: improved VoiceOver support and accessibility labels for posts, items, and notifications; dynamic labels for Like/Comment actions; improved grammar and announced unread counts for notifications. - Feed view fixes: reverted to a single feed and removed the friend/global feed toggle. - UI/chart sizing improvements: refined impact chart sizing and Y-axis tick formatting for clearer metrics. - Password reset flow enhancements and testing; Registration password validation: added reset password with input validation and a password strength indicator; added unit tests for reset password modal; blocked registrations with weak passwords. - Descriptive label for waste type filter: added a descriptive label and translations (English/Turkish) above waste-type filter controls. - Integrate report API endpoint for posts and comments: added submitReport() and API wiring; updated context to include objectId; supported report types (Spam, Hate Speech, Violence, Other); included endpoint/test scaffolding. - Resolve type mismatch using as any: added safe casts to progress refactor work and reduce blockers. - Test coverage for modules: added ReportModal interaction tests; added tests around reset password and report flows. - Notification support for report moderation actions: added notifications for moderation events with privacy considerations and translations. - Report notification UX: added preview for report notifications and read-on-click behavior; disabled post previews within report notifications. - Fix rendering of badge icons: ensured badge icons render correctly in mobile UI. Major accomplishments and impact: - Substantial improvement in user experience and reliability of notifications, moderation workflows, and critical account flows. - Concrete progress toward backend integration readiness (reporting) with client-side wiring and tests. - Accessibility and localization enhancements that broaden reach and compliance; better data visualization and exploration surfaces for product metrics. Technologies and skills demonstrated: - Mobile development with React Native and TypeScript; API integration; unit and interaction test coverage. - Accessibility best practices (VoiceOver, dynamic labels, semantic announcements) and performance-conscious UI tweaks. - Localization/i18n for English and Turkish; robust input validation, password strength logic, and secure UX patterns. - Observability through UI-level QA, with bug fixes around badges and previews to ensure consistent UX.
