Sudhir Kumar | Java Full Stack Developer

Who I Am

About Me

I'm a Java Full Stack Developer from Bengaluru with hands-on internship experience building production-grade backend and full-stack applications. I specialise in Spring Boot, Hibernate (JPA), MySQL, and RESTful API development.

During my internship at KodNest Technology, I contributed to real-world projects — designing APIs, optimizing SQL queries, implementing JWT-based security, and collaborating in Agile sprints. I believe in writing clean, maintainable code and love solving complex backend challenges.

I hold a B.Tech in CSE (AI & ML Specialization) from Technocrats Institute of Technology & Science, Bhopal with a CGPA of 7.74. I'm actively seeking an Associate Software Engineer role to make a meaningful impact.
