India

Message

At Binary, I developed enterprise web applications and built a reusable UI component library that reduced development time by 30%. I also engineered a location-aware advertising system that used live GPS data to trigger ads based on taxi positions.

For the taxi-top fleet platform, I developed Node.js APIs and MongoDB data models, and enabled real-time device updates with Socket.io. At WPS Technologies Pvt. Ltd., I developed React applications, integrated APIs, built interactive maps, and mentored junior developers through code reviews.
