- Multi-stage builds for all 4 services (api_gateway, backtesting, ml_training, trading) - Optimized layer caching for faster rebuilds - Reduced image sizes with cargo chef pattern - Added Dockerfile.simple for minimal testing builds - Updated docker-compose.yml with health checks - All services validated building successfully (Agent 18, 33)
