Hi, I’m a Java Technical Lead and tutor with extensive industry experience in building enterprise applications.

I teach Java from fundamentals to interview and architect level, with a strong focus on understanding how and why things work, rather than only memorizing syntax.

My training covers:

- Core Java – OOP, Collections, Generics, Exception Handling, Java 8+ features, Streams, Multithreading, Concurrency, CompletableFuture, JVM and performance tuning
- Spring End-to-End – Spring Boot, REST APIs, Spring Data JPA, Hibernate, Transactions, Spring Security, Microservices, Kafka, Redis and testing
- DSA in Java – Arrays, Strings, Two Pointers, Sliding Window, Linked Lists, Stack, Queue, Trees, Graphs, Heap, Recursion, Backtracking and Dynamic Programming
- Low-Level Design – OOP modelling, SOLID principles, design patterns, class/interface/record design, database design and REST API design
- High-Level/System Design – Microservices architecture, scalability, caching, Kafka, distributed transactions, Saga, Outbox, Kubernetes, resilience, security and observability
- Interview Preparation – Coding rounds, Java/Spring interview questions, system-design discussions and real-world scenario-based questions

My teaching approach is simple: start from the basics, understand the problem, learn how to think about the solution, write the code, and then gradually move to production and architect-level scenarios.

The goal is not just to clear an interview, but to develop the confidence to design, code, debug and explain real Java systems.
