About

I'm a results-driven Software Engineer with a passion for building efficient, scalable systems. Currently pursuing my B.Tech in Computer Science at Dr. A.P.J. Abdul Kalam Technical University, I've gained hands-on experience architecting real-time applications and cloud infrastructure.

As an Associate Software Engineer at AARFID, I've architected and deployed RFID tracking applications serving 50+ concurrent users with 99.9% uptime. I specialize in ASP.NET Core, Node.js, and modern DevOps practices, with proven expertise in API integration, database optimization, and CI/CD automation.

I'm fascinated by the intersection of scalability, performance, and elegance in software design. When I'm not coding, you can find me competing on LeetCode, exploring new technologies, or contributing to open-source projects.
