A structured, hands-on record of my transition from a MERN background into Java and Spring Boot backend development.
I'm Sourav Kumar, a B.Tech CSE student, currently backend-focused with production experience in Node.js/Express/MongoDB and now building deep Java + Spring Boot skills. This repo tracks that progression — Maven, JDBC, Hibernate, Spring Core, Spring Data JPA, and Spring Security — with runnable code for each concept as I learn it, not just course notes.
