I’m a backend-focused Software Engineer with production experience building scalable REST APIs and microservices using Java, Spring Boot, and AWS. I enjoy turning complex payment and event flows into reliable, customer-focused services.

At Hulk HireTech as a “Java Developer (Trainee),” I built core REST API integration with PayPal Standard Checkout in a microservices architecture hosted on AWS. I implemented OAuth 2.0 security, centralized error handling, circuit breaker fault tolerance, and distributed logging using Micrometer.

I also enhanced performance and reliability by integrating Redis for cache-based token management and Apache Kafka for asynchronous payment event communication to merchant systems. I backed my work with unit tests using JUnit and Mockito to maintain high code coverage and reduce production defects.

In my “FoodOrder Application” project, I designed and developed 15+ REST API endpoints for cart management and real-time order tracking using Spring Boot, Spring Security (JWT), and JPA/Hibernate with MongoDB. I delivered full test coverage across endpoints and the service layer while following Agile practices and shipping modular, maintainable designs.
