THE_PROBLEM

Building a production SaaS platform that combines AI-powered content generation with real-time SEO rank tracking. System needed to handle concurrent AI requests, process large datasets, and maintain sub-second response times for end users. Multi-tenant architecture with workspace isolation required from day one.

THE_APPROACH

  • Migrated to Next.js 14 App Router with React Server Components for optimized rendering
  • Implemented PostgreSQL with row-level security for multi-tenant data isolation
  • Integrated OpenAI GPT-4 API with rate limiting, fallback handling, and streaming responses
  • Built real-time rank tracking system with external API orchestration and caching
  • Set up Redis caching layer for frequently accessed data and job queue management
  • Deployed serverless edge functions for API endpoints with automatic scaling
