  • Node.js (NestJS) + PostgreSQL: API-heavy, real-time or high-throughput integrations
  • OpenSearch/Elasticsearch: complex customer search, fuzzy matching, reporting filters
  • AWS ECS/Lambda: cost-efficient scaling, reliable background jobs, secure private networking
  • Snowflake/Redshift: analytics layer when reporting goes beyond operational CRM
