Project overview:

• Develop a secure assessment mode for an educational mobile app that allows students to take exams without distractions and without leaving the application environment.
• Aim to improve academic integrity while preserving user privacy and ensuring a smooth learning experience.

Scope & core features:

• App-level restricted navigation: prevent module switching during an exam and disable non-authorized features while the exam is active.
• Local encrypted data storage and offline submission: securely store answers locally when offline and submit/synchronize results when connectivity is restored.
• Teacher/administrator dashboard: schedule, launch, and monitor exams (real-time monitoring and basic analytics for invigilation).
• Adaptive exam session recovery: robust recovery and continuation of exam sessions after connectivity loss, with conflict resolution when syncing.

Technical stack & tools (suggested):

• Mobile app: React Native / Expo; local storage options: Secure Storage, SQLite, IndexedDB where applicable.
• Backend / API: Node.js with Fastify or NestJS; databases: MongoDB or PostgreSQL; Auth: Firebase Auth or Auth.js.
• Deployment & tooling: Render / Railway / Vercel for deploys; Git + GitHub for version control.

Responsibilities & candidate profile:

• Required profile: Full-Stack Developer 25 (implement front-end mobile features and backend APIs, ensure secure storage and synchronization flows).
• Tasks include designing the restricted-navigation UX, implementing encryption for local storage, building APIs for scheduling/monitoring exams, and ensuring reliable offline-first behavior.
• Additional responsibilities: integrate authentication, implement server-side monitoring endpoints for teachers/administrators, write tests, and document recovery/sync strategies.

Deliverables & evaluation criteria:

• A functioning React Native prototype with exam-mode restrictions and offline encrypted storage.
• Backend endpoints and a basic teacher/administrator dashboard to schedule and monitor exams.
• Demonstrated adaptive session recovery after connectivity interruptions and secure submission flow.
