Enhanced a smart-store monitoring application for Nilgiris outlets to track rack status and customer behaviour.

Added suspicious-customer activity detection and visual alerts to improve store security and operational efficiency. Developed and maintained React.js applications with reusable components, responsive interfaces and REST API integration. Worked with product, design and backend teams to translate requirements into practical, user-focused features and production-ready UI flows. Built a real-time monitoring web application covering 500+ Domino’s stores, providing centralized visibility into store activity. Implemented dashboard features for AI-based theft detection, gender-wise footfall, staff compliance and suspicious-activity alerts. Integrated visual annotation and detection results into the UI to make AI-generated store events easier to review and act on.
