- AI-powered healthcare assistant platform enabling real-time patient engagement, clinical decision support, and intelligent care workflows. - Led the end-to-end backend modernization of a legacy healthcare engagement system into a scalable, cloud-native microservices architecture. - Migrated monolithic APIs into event-driven microservices using asynchronous messaging (Kafka / RabbitMQ)

- Designed and delivered a multi-tenant IoT SaaS platform that enables enterprises and municipalities to connect, monitor, and analyze real-time data from distributed devices (sensors, vehicles, industrial machines). - Built a scalable SPA dashboard using React + TypeScript for real-time IoT data visualization, implemented real-time updates using WebSockets for live telemetry streams.

- Developed and maintained full-stack features using React.js, Node.js (Express), and MongoDB, ensuring high performance and seamless user experience across desktop and mobile environments. - Architected and implemented RESTful APIs to support dynamic data exchange between frontend and backend systems, enabling real-time updates for task tracking and internal communication modules.

- Built Python (Flask) backend services and REST APIs backed by PostgreSQL, applying clean layering, input validation, and basic authentication patterns for internal training projects. - Developed React single page applications that consumed backend APIs, implemented reusable components and state management, and delivered responsive UI for an internal HR portal with full CRUD workflows. - Implemented a small recommendation system using Python, scikit learn, and simple feature engineering.
