Migrated from Fitbit platform to Garmin SDK to enhance accuracy of health metrics such as skin temperature, sleep patterns, and heart rate. Implemented AWS Timestream to efficiently store and query time-series data from Garmin devices. Utilized a Dockerized Java Spring Boot service to process and analyze incoming health data files. Designed and implemented a real-time alert system that monitors patients’ vitals and sends notifications to the frontend app when heart rate exceeds normal thresholds. Added a facility-based wearable management feature through an admin panel web portal developed with React.js and MUI. Designed cross-platform interfaces in React Native (Expo, TypeScript) to deliver real-time health visualizations and streamline facility management workflows. Implemented GraphQL for unified schema handling, queries, mutations, and real-time data streaming via subscriptions. Integrated a Python Flask ML service to predict comfort values from wearable data and patient informat

Developed reusable and modular web components using React.js, TypeScript, and Material UI to ensure consistency and scalability. Created RESTful API endpoints with Node.js, Express, and TypeScript to process, transform, and deliver backend data in JSON. Designed a logic-based system to dynamically process trading card data according to user parameters and filters. Implemented a CSV export feature for integration with third-party POS systems. Managed MySQL interactions with Prisma.js ORM for efficient, type-safe access. Added server-side validation, robust error handling, and structured logging to support debugging and client messaging. Used Git and Bitbucket for version control and collaboration.

Built responsive forms and UI components for hospital equipment using Material UI and Tailwind CSS. Developed dynamic forms that render fields based on equipment type, leveraging React state management and conditional rendering. Integrated form submissions with backend APIs using Fetch, with feedback handling and error messages. Utilized Formik + Yup for form state and validation. Created equipment models with Sequelize ORM (PostgreSQL) to define device types and maintenance data. Built RESTful APIs for CRUD operations, added input validation with Zod, and implemented a notification system using node-cron and Nodemailer to remind maintenance teams.
