Mastering Backend Engineering

Java + AWS + System Design + Microservices

This intensive 8-week program transforms professionals into cloud-ready backend engineers for top product companies. Mastering Java, Spring Boot, and AWS, you’ll advance from SOLID principles to building resilient Microservices. The hands-on curriculum covers System Design, database optimization with PostgreSQL and Redis, and asynchronous messaging via Kafka. You’ll conclude by deploying scalable applications using Docker and AWS (EC2/S3). By bridging the gap between coding and architecture, you’ll gain the production-grade skills needed to design, secure, and scale modern distributed systems.
