Full Stack Web Developer

I’m looking for a full-stack developer to build a web-based aviation exam practice system. This platform will allow users to log in with Google, choose a PPL or IREX practice exam, take AI-generated multiple-choice tests, and track their progress.

The system should be mobile-friendly, secure, and scalable. It will integrate Google Sign-In (Firebase Auth), OpenAI API (for AI-powered questions), and PostgreSQL (for user data and exam storage).

Key Features:
User Authentication – Google Sign-In with Firebase
Exam Selection – Choose PPL, IREX, or future CASA exams
AI-Powered Question Generation – OpenAI API (GPT-4) pulls questions from a knowledge base
Live Exam Interface – One question at a time, instant feedback, progress tracking
Scoring & Progress Tracking – Users review answers & see past scores
Admin Dashboard (Optional) – Upload new questions, view user performance

I will send you a full description.
