Abhinav Kumar — Backend Engineer

I’m a Java Backend Developer passionate about building scalable, secure, and efficient backend systems that solve real-world problems. With over 2 years of professional experience in Spring Boot, REST APIs, and Microservices, I’ve developed a strong foundation in backend architecture, database optimization, and cloud-ready deployments. At Mirra Healthcare, I design and maintain production-grade Spring Boot microservices supporting critical healthcare operations. I’ve implemented JWT and Spring Security for secure authentication, optimized SQL queries to improve performance by 25%, and automated build & deployment pipelines using Docker and GitHub Actions. My focus has always been on writing clean, maintainable code and ensuring high reliability in production systems. I’m well-versed in the Spring ecosystem (Spring Boot, Spring MVC, Spring Data JPA, Spring Security) and have hands-on experience with MySQL, PostgreSQL, and MongoDB. I also integrate tools like JUnit, Mockito, and Postman to build robust test environments that keep systems stable and scalable. In my personal project, the Digital Queue Management System (DQMS), I built a complete backend using Spring Boot, WebSocket, and JWT, enabling hospitals and banks to manage live queues efficiently. This project helped me deepen my knowledge of real-time communication, concurrency handling, and database optimization. Beyond the code, I value collaboration and clarity — working closely with teams across QA, DevOps, and product to deliver end-to-end solutions. I enjoy debugging complex issues, mentoring peers, and learning continuously to stay current with evolving backend technologies.
