About

I’m a Software Engineer passionate about building scalable, reliable backend systems and user-friendly web applications. I recently graduated with a B.Tech in Information Technology (CGPA 9.30) from IIIT Sonepat, and gained hands-on experience through internships at PayPal and uSthaan Solutions, contributing to high-impact projects in performance optimization, observability, and system architecture. At PayPal, I worked on tech-excellence initiatives — analyzing and improving Customer Perceived Latency (CPL) and building observability dashboards to enhance system reliability. At uSthaan, I designed scalable backend services and improved code modularity to support real-time order processing across platforms. I actively explore new technologies and stay current with industry trends, with particular interest in backend engineering, distributed systems, and cloud-native development. Always ready to connect with like-minded people and how we can achieve great things together.
