What I built

Core learning-platform modules with React and Express.
Responsive, interactive UI with TanStack Query managing client-side state for a real-time feel.
AI quiz generation with OpenAI models through LangChain, on a PostgreSQL schema modeled with Prisma.
Leaner API endpoints and JSON payloads to cut response time.
