Java Internship Experience

Enterprise Java.
Real Production Code.

You won't be building standalone apps in isolation. You'll work inside a real Java team using Spring Boot, Hibernate, Kafka, and AWS — exactly how TCS, Infosys, and Wipro Java teams build enterprise software every day.

🏗

Multi-module Maven project — Services, Repositories, Controllers, DTOs, Mappers — with daily PR reviews from senior Java architects.
📨
Kafka Event-Driven Architecture
Build real Kafka producers and consumers — publish domain events, handle async processing, and manage consumer groups in a live environment.
☁️
Deploy to AWS ECS / EKS
Dockerise your Spring Boot app, push to ECR, deploy to ECS with load balancers — your code runs on real AWS infrastructure with real monitoring.
📜
Java Portfolio + Certificate
GitHub repos with Spring Boot microservices, AWS-deployed URLs, JUnit coverage reports, and a senior mentor endorsement for your LinkedIn.

Real Java track alumni. Real Spring Boot apps they built. Real offers that changed their careers.

The TCS Java CoE interviewer asked me to walk through a Spring Boot service I'd written. I opened GitHub, showed the Hibernate entities, the Kafka producer, and the JUnit tests. They said it was the cleanest Java code they'd seen from a fresher. Got the offer the same evening.

Working with Kafka during the internship was completely different from anything I'd read about. Building real producers, managing consumer groups, handling failures — that practical experience made my Infosys interview feel like a normal conversation about work I'd already done.

I switched from a data entry job to Java development at 27. The microservices project I built — 7 Spring Boot services on AWS EKS with Kafka — was what Wipro's Java team couldn't believe. Nobody expected a career switcher to have that. The portfolio did all the talking.

The daily code reviews were brutal in the best way. My mentor would tear apart my Hibernate queries, explain N+1 problems, and force me to fix them with proper fetch strategies. At Accenture, when they asked about JPA optimisation in the interview, I had real examples — not textbook answers.

Deploying my Spring Boot app to AWS ECS for the first time during the internship felt impossible. By week 10, I was doing it automatically as part of the CI/CD pipeline. HCL asked me about AWS deployment in my interview — I walked them through the exact pipeline I'd built. Offer in 2 days.

Writing 88% JUnit test coverage with Mockito and Testcontainers was the skill that surprised Capgemini most. Every other fresher they interviewed said they'd done unit testing — I could show real tests, real mocks, real integration tests running against a Docker PostgreSQL container.
