About Rebhu Roy
I’m a **Back-End Developer** with hands-on industry experience in building scalable websites and web applications. I specialize in **Java** with **Spring Boot**, and I enjoy designing robust back-end architectures and APIs. My skill set spans across **PostgreSQL**,**NoSQL databases** like **MongoDB** and **Firebase/Firestore**, and I also have experience with **Node.js**,**PL/SQL**, and working in **Unix environments**. On the front-end side, I’m comfortable with **JavaScript, HTML, CSS, and Bootstrap**, ensuring smooth integration between UI and back-end services. Currently, I’m exploring **GraphQL with Spring Boot** to build more flexible and efficient APIs. I’m passionate about solving complex problems with clean, maintainable code and always eager to learn and adapt to new technologies. Take a look at my work or feel free to get in touch — I’d love to collaborate!
