I’ve worked on core components of Razorpay’s POS firmware systems, focusing on OTA (Over-The-Air) upgrade mechanisms, cursor rule optimization, and secure transaction flows.During my internship, I- Led the OTA module development, improving update times across devices by 40%- Designed a custom SQR payment device with 10+ integrated features, enhancing speed and reliability- Optimized device configuration using cursor rules, reducing dev cycles from 20 to 7–8 days- Built a unit testing framework covering 80% of embedded code to catch early bugs and improve QA.Outside work, I\'m deeply involved in competitive programming, with a peak LeetCode rating of 2145 (Knight) and 1588 on Codeforces (Specialist). I\'ve also built full-stack projects like a food delivery app and a Dijkstra-based route planner using React, Node.js, and C++.Currently, I\'m looking for full-time Software Developer roles where I can apply my experience in backend systems, embedded tech, and full-stack development to build reliable and scalable products.
