Build a Complete Android School Performance Tracking App MVP

We are looking for a skilled freelancer to develop an Android APK for school performance tracking. The app should include features such as authentication for admin and teachers, student management, marks management with automatic performance analysis, attendance tracking, dashboards with performance insights, and PDF report generation. The app must be built using Flutter for the frontend, Node.js + Express for the backend, and PostgreSQL as the database. The design should be clean, modern, and mobile-responsive with clear indicators for student performance levels (strong, average, weak). Deliverables include a working APK, full source code, database schema, API routes, and setup instructions.
