• Frameworks: Spring Boot
  • Spring Web
  • Spring Cloud (Eureka, Config Server, API Gateway)
  • Spring Validation
• Tools:
  • Feign Client and Web Client for inter-service communication
  • Eureka Server for service discovery
  • Spring Cloud Config Server for centralized configuration
  • Zipkin for distributing tracing
  • Apache Kafka
• Build Tool: Maven
• Database: (MySQL/MongoDB/PostgreSQL)
