About Niraj Kumar
I am a Software Engineer with 2.5+ years of experience in building secure, scalable, and high-performance backend systems using Java and Spring Boot. My expertise spans RESTful API development, microservices architecture, SQL databases, JPA/Hibernate, and API security, with a strong focus on delivering reliable and maintainable enterprise solutions.I have contributed to large-scale, production-grade applications in the banking and government domains, where I designed and implemented backend services, integrated external systems, and ensured compliance with security and regulatory standards. I have hands-on experience with Kafka-based asynchronous processing, JWT-based authentication, and API gateway integrations, enabling fault-tolerant and scalable workflows.In addition, I have improved system reliability and development efficiency through comprehensive unit testing (JUnit & Mockito), CI/CD automation using Jenkins, and backend performance optimization. I am also experienced in handling production issues, optimizing database queries, and collaborating closely within Agile teams to deliver high-quality releases.Passionate about backend engineering and system design, I enjoy working in challenging environments that encourage continuous learning, clean architecture, and impactful problem-solving.
