About

Java Backend Developer with 5+ years of overall IT experience, including 3+ years of hands-on experience building scalable backend systems using Java 17 and Spring Boot. I specialize in designing and optimizing RESTful APIs that handle high-volume transactions (1000+ daily requests), with a strong focus on performance, reliability, and clean architecture. I have successfully improved backend data processing performance by 30% and reduced database latency by 25% through query optimization and efficient system design. My experience includes working with PostgreSQL, Spring Data JPA, Hibernate, Docker, and Linux environments. I also have a strong background in resolving production issues, improving system stability, and ensuring high-quality releases through unit and integration testing using JUnit and Mockito. I started my career in Manual Testing, which gives me a strong edge in debugging, understanding system behavior, and building robust backend systems. I am currently looking for opportunities as a Java Backend Developer in product-based companies where I can contribute to building scalable, high-performance applications.
