• Offline-first architecture: local SQLite storage, encryption at rest, and data synchronization
• Device hardware integration: camera, barcode/QR scanning, signature capture, GPS
• Authentication with OIDC/OAuth 2.0 (Okta or comparable) and secure token storage
• REST API integration against backend services
• Mobile testing with Jest and an E2E framework such as Detox or Maestro
