Optimization Recommendations

High Priority

1. Connection Pooling: Implement for better concurrent request handling
2. Response Caching: Cache frequently accessed endpoints (inventory, contacts)
3. Async/Await Pattern: Consider for handling 1000+ concurrent users

Medium Priority

1. Meilisearch Integration: Complete production setup for enhanced search
2. APM Monitoring: Deploy New Relic, Datadog, or Prometheus for production tracking
3. Query Profiling: Regular monitoring of slow query logs

Low Priority

1. GraphQL Layer: Consider if API versioning becomes needed
2. Request Batching: Implement for client-side performance optimization
3. CDN Integration: For static asset delivery
