Core Java
Learn Core Java in English with strong fundamentals, object-oriented programming, collections, Java 8, interview readiness, and a bridge toward Spring Boot.
Get the full learning path in the right order: Core Java, Spring Boot, Microservices, plus 2 production-grade HRMS projects included as add-ons.
Tamil backend roadmap with Core Java, Spring Boot, Microservices and 2 included production-grade HRMS projects.
English backend roadmap with Core Java, Spring Boot, Microservices and 2 included production-grade HRMS projects.
This page is organised in the order learners should actually study: foundation first, backend next, distributed systems later, then real project implementation.
Begin with syntax, OOP, collections, Java 8 and interview-ready fundamentals before moving into backend development.
Learn Core Java in English with strong fundamentals, object-oriented programming, collections, Java 8, interview readiness, and a bridge toward Spring Boot.
Continue with REST APIs, JPA, validation, security, JWT and real backend structure after Core Java is clear.
Learn Spring Boot in English with REST APIs, JPA, validation, security, JWT, testing, deployment, and production-ready backend structure.
Go deeper into service decomposition, Eureka, Gateway, resilience and distributed-system thinking.
Learn Java Microservices in English with Spring Boot, service decomposition, communication patterns, Eureka, Gateway, Config Server, resilience, security, and deployment basics.
Use HRMS production-style projects to convert concepts into practical backend implementation.
Build a production-grade HRMS monolithic backend project in English with authentication, employee management, attendance, leave flow, payroll, and real project architecture.
Build a production-grade HRMS Microservices backend project in English with Eureka, Gateway, JWT, OpenFeign, Resilience4j, service-wise databases, and reporting APIs.
Core Java comes first so learners understand Spring Boot with confidence instead of memorising annotations without language clarity.
Microservices make more sense only after REST APIs, validation, persistence, security and application structure are already clear.
Production-style HRMS projects help learners apply concepts after the core backend track becomes comfortable.
