About Me.

Hey 👋,

I'm Ritik Raj, currently pursuing my Master's in Computer Applications from Vellore Institute of Technology, Vellore. I come from a strong computer applications background, and I'm building my career around web development and problem solving.

I primarily work with Core Java and the Spring ecosystem (Spring Boot, Spring Core, Spring Security, Spring Data JPA, Hibernate). Alongside that, I've explored databases (such as MySQL and MongoDB,) cloud services (AWS EC2, S3, Elastic Beanstalk, Lambda), and containerization (Docker).

I enjoy problem-solving and have solved over 500 Data Structures and Algorithms problems on LeetCode, achieving a 1600+ contest rating and earning over 14+ badges.
