Bilingual Offline-First Mobile Application — React Native

Built using React Native, Redux Toolkit, WatermelonDB, and i18next. This is the mobile client for a multi-tenant industrial maintenance ERP, supporting full Arabic and English bilingual interfaces across every screen, form, and navigation flow. Implemented offline-first data sync using WatermelonDB, allowing operators and technicians to complete maintenance checklists and log equipment repairs with no internet connection — all data is stored locally on the device and automatically synced to a Node.js/PostgreSQL backend once connectivity returns, with conflict resolution handled on reconnect. The app supports role-based navigation for four different user types (operator, technician, supervisor, admin), each with a tailored interface and permission set.
