Building Production Apps with SERN: Real-World Lessons in Full-Stack Architecture and Infrastructure

This case study delivers practical insights into building scalable web applications with modern tools, covering critical architecture decisions from Supabase's PostgreSQL foundation to global deployment via Vercel and Cloudflare's CDN. The lessons extend far beyond this Quran app—developers will gain actionable knowledge on service integration, performance optimization across devices, and infrastructure strategy. The core takeaway challenges common over-engineering: shipping first and iterating with real user feedback outweighs perfectionism in production environments.
