🚀 Node.js Backend, Microservices & Cloud

Master modern backend engineering with an updated syllabus that now includes gRPC and production-grade security using HashiCorp Vault, AWS SSM Parameter Store, and AWS KMS.

This program is designed to help you build production-grade, scalable, secure, and cloud-ready backend systems with real-world architecture patterns, deployment workflows, and interview-focused learning.

🔥 Recommended Placement for New Topics

✅ Add gRPC after the Microservices module

Because it naturally fits with inter-service communication, internal contracts, and high-performance service-to-service calls.

✅ Add Production-Grade Security after Auth & RBAC and before Deployment

Because secret management, encryption, and secure configuration handling are core platform concerns before moving into cloud deployment.

✅ Mention AWS KMS again in the AWS Deployment module

To connect the security concepts with real production implementation on AWS.
