About Nishant Raj

I’m a Java Backend Developer with around 4 years+ of experience building reliable and scalable backend systems.Currently, I work at TCS, and previously at Tech Mahindra, where I gained hands-on experience solving real-world backend engineering problems in enterprise environments. My core expertise lies in Java (Core Java, Java 8, and Java 21), along with RESTful API development, concurrency, and backend system design fundamentals.I’ve worked extensively with SQL databases, backend logic design, and production-grade development practices, with a strong focus on performance, stability, and clean, maintainable code. I enjoy debugging complex issues, improving system behavior, and continuously refining the quality of the systems I work on.My broader skill set includes system design, DBMS, data structures and algorithms, and exposure to cloud platforms such as AWS, applied while solving real-world backend engineering challenges.Beyond my day-to-day role, I’m interested in engineering best practices, system design, and continuous learning. I also enjoy sharing insights around technology, personal growth, and lessons learned from practical development experience.I’m always open to connecting with professionals who value strong engineering fundamentals, thoughtful problem-solving, and building meaningful software.
