• Security: Arcjet protection, input validation, rate limiting

🧩 Key Challenges & Solutions

Challenge 1: Real-time Course Progress Tracking

Problem: Needed to track and display user progress across courses without page refreshes. Solution: Implemented a WebSocket-based real-time update system that syncs progress across devices instantly while maintaining data consistency with optimistic UI updates.

Challenge 2: Secure File Uploads

Problem: Required a secure way to handle course material uploads while preventing unauthorized access. Solution: Built a system using AWS S3 presigned URLs with temporary access tokens, file type validation, and virus scanning integration, reducing unauthorized access attempts by 99%.
