Executive Architectural Summary

Explore how NestJS TypeScript microservices, AWS Lambda serverless functions, and SQS message queues process high-throughput financial transactions.

Monolithic backend applications hit scaling limits when single database bottlenecks impact unrelated service modules.

By decoupling business logic into lightweight NestJS TypeScript microservices running on AWS EKS and ECS Fargate, we achieve independent autoscaling.

In a recent fintech project, our event-driven Node.js architecture processed over 100K daily active collaborators with 99.99% system uptime.
