Java Full Stack Trainer (Spring Boot + React / Angular)

About the role

Java full stack (Spring Boot with React or Angular) is the most hired stack in banking, insurance, manufacturing and large enterprises, because legacy systems are being modernised layer by layer. Employers expect microservices, security, containers and cloud basics — not just syntax. You will teach learners to build and deploy an enterprise-style application and to clear Java interviews with confidence.

Why this role matters now: Java with Spring Boot and React or Angular remains the most hired enterprise stack in banking, insurance and manufacturing, and employers now test microservices, security, containers and cloud basics, not only syntax.

What you will do

• Deliver live online Java full stack batches from Core Java to a deployed microservices project
• Teach OOP, collections, streams, concurrency and design patterns with interview-style problems
• Guide an enterprise capstone: Spring Boot services, secured REST APIs, a React / Angular front end, database, Docker and CI/CD
• Review assignments and code, give structured feedback and run mock interviews and DSA practice
• Keep content current with Java 17+ and Spring Boot 3
