Yuvraj Singh

I build responsive web applications and backend systems, from interactive React experiences to secure full-stack platforms.

During my Specialist Programmer internship at Infosys, I developed a real-time notification system with Spring Boot, Apache Kafka, and SSE. I implemented priority-based processing with Kafka topics and consumer groups, and integrated REST APIs with PostgreSQL.

I’ve built a MERN trip booking platform and a job application tracker with JWT authentication, role-based access, email alerts, filters, and charts. I also created a React sorting visualizer for Bubble Sort, Merge Sort, and Quick Sort animations while optimizing state management to reduce re-renders.

I’m a HackWithInfy’25 finalist in the top 0.01%, placed in the top 10 at the Dexterrix 4.0 Hackathon, and hold a 1400+ LeetCode rating.
