Next.js with App Router +- Backend: NestJS (modular monolith) +- Database: PostgreSQL with Prisma +- Cache: Redis +- Deployment: Single container or serverless + +**Why**: Start simple, organize by domains, easy to split later + +### Pattern 2: JAMstack with Serverless Functions +**When**: Content-heavy sites, marketing sites, blogs with dynamic features +**Stack**: +- Frontend: Next.js (static export) or Astro +- Backend: Serverless functions (Vercel, Netlify) +- Database: Planetscale, Supabase, or Firebase +- CMS: Contentful, Sanity, Strapi +- Deployment: Vercel or Netlify + +**Why**: Excellent performance, cost-effective, great DX + +### Pattern 3: SPA with REST API +**When**: Admin panels, internal tools, dashboards +**Stack**: +- Frontend: React with Vite, React Query +- Backend: Express or Fastify +- Database: PostgreSQL +- Deployment: Frontend (Vercel), Backend (Railway/Render) + +**Why**: Simple, flexible, well-understood pattern + +### Pattern 4: Real-Time
