Nannepaga Kalyan Babu

I am a Backend Software Engineer with 3+ years of industry experience at CGI Inc., a global IT services company, working on enterprise banking applications used by major US financial institutions. My key skills are Core Java, Java 8–17 features, Spring Boot, Spring Framework, REST API development, Apache Kafka, Microservices architecture, SQL (PostgreSQL, MySQL, Oracle), MongoDB, JUnit and Mockito testing, Git, Docker, and Kubernetes. I have received multiple company awards for technical excellence, including the CGI Star Award and Bronze Medal, and I was recently selected for CGI’s AI Fast Track program, where I build AI-powered applications using Java and Spring AI. I teach Core Java, OOP concepts, Collections, Exception Handling, Multithreading, Java 8 Streams and Lambdas, Spring Boot, and REST API development — from absolute basics to interview and placement preparation. My teaching approach is practical and beginner-friendly: I explain concepts with real industry examples, live coding, and hands-on exercises, the same way problems are solved in actual software companies. Whether you are a college student preparing for placements, a fresher starting your first job, or a working professional switching to Java backend development, I can help you build strong fundamentals and real-world coding confidence.
