About Me

Hello! I'm Rahul — a Software Development Engineer based in New Delhi, currently building scalable systems at WinZO.

I graduated from the National Institute of Technology, Kurukshetra with a CGPA of 9.56/10 in Computer Engineering, where I developed a strong foundation in systems, algorithms, and problem solving.

At work, I enjoy building reliable and high-performance applications, working across the stack with a focus on scalability, performance, and clean, maintainable code.

Outside of work, I’m deeply interested in competitive programming. I’ve been an ICPC Regionalist and achieved Expert on Codeforces and Knight on LeetCode, constantly pushing my problem-solving skills.

Technologies I work with:

JavaScript / TypeScript
React.js / Next.js
Node.js
PostgreSQL
Redis / MongoDB
Docker / Jenkins
C++ / Java / Python
Git
