// System Diagnostics & Performance Metrics
// Core Pipeline & Systems Architecture Flow
Sequential data ingestion, processing, representation model routing, and generation steps.
Client Application
React.js client captures student requests and handles global state.
Express.js Router
Routes incoming API calls, validated by JWT security middleware.
Aggregate Controller
Fetches optimized courses data using MongoDB aggregate lookup pipelines.
MongoDB Database
Persists transactional profiles, enrollment records, and course info.
Technical Obstacles
Securing role-based course monetization while maintaining fast loading of media assets. Slow API routes due to deep MongoDB population queries.
Engineering Solution
Created strict JSON Web Token (JWT) auth middleware, optimized MongoDB aggregate pipelines with indexed search, and integrated lazy loading/assets compression to maximize rendering speeds.
