Root cause of 502 errors under 30 concurrent users: the production server was running dev-mode infrastructure (Vite dev server, NestJS --watch, no DB connection pooling, single Node.js process). Changes: - backend/Dockerfile: multi-stage prod build (compiled JS, no devDeps) - frontend/Dockerfile: multi-stage prod build (static assets served by nginx) - frontend/nginx.conf: SPA routing config for frontend container - docker-compose.prod.yml: production overlay with tuned Postgres, memory limits, health checks, restart policies - nginx/production.conf: keepalive upstreams, proxy buffering, rate limiting - backend/src/main.ts: Node.js clustering (1 worker per CPU, up to 4), conditional request logging, production CORS - backend/src/app.module.ts: TypeORM connection pool (max 30, min 5) - docs/DEPLOYMENT.md: new Production Deployment section Deploy with: docker compose -f docker-compose.yml -f docker-compose.prod.yml up -d --build Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
