The Silent Foundation: Critical Infrastructure Decisions Behind Successful AI Platforms

Backend infrastructure for AI platforms often goes unnoticed until it fails—but thoughtful design decisions at the database layer can prevent security incidents and ensure scalability. This account of EduRag's architecture demonstrates how Supabase PostgreSQL with Row Level Security, combined with proper schema design, creates a foundation where developers can build features confidently without worrying about data exposure or performance bottlenecks. For engineers building AI applications, understanding these foundational decisions is the difference between a system that works and one that scales.
