Work Experience

Software Engineer at Hint Health
January 1, 2024 - May 1, 2026
Led adoption of Generative AI and LLM technologies across healthcare products and clinical workflows, architecting LLM-powered medical chatbots using RAG, vector search, embeddings, semantic retrieval, prompt engineering, and context validation. Architected self-hosted LLM inference infrastructure with semantic caching and optimized retrieval pipelines to improve response performance, scalability, cost efficiency, and data privacy. Led design/development of a secure, scalable IoT and real-time data platform integrating wearable devices for signal processing, ML, and analytics to extract physiological biomarkers and generate actionable insights (cardiovascular, sleep, obesity, CNS). Integrated AI, analytics, and real-time patient data capabilities with the Hint Health platform for end-to-end clinical/care management and operational insights. Designed and deployed containerized, cloud-native microservices and reusable components with strong data isolation, scalability, reliability, and f
Full Stack AI Engineer at Wayfair
April 1, 2020 - December 1, 2023
Worked on AI-powered e-commerce solutions to improve online shopping experience for furniture and home goods. Leveraged LLMs, NLP, machine learning, RAG, and vector/embedding search for intelligent search, personalized recommendations, and customer engagement. Built RAG pipelines combining SQL and vector search to retrieve relevant product information before using LLMs to generate grounded, contextual responses (e.g., attribute-based intent matching for natural-language product queries). Designed asynchronous architectures using queues/service bus/pub-sub patterns to manage AI latency and API rate limits while keeping customer-facing applications responsive. Implemented caching and optimized backend services for performance and reliability. Contributed to scalable cloud deployments across Azure, AWS, and GCP, supporting API development, data processing, CI/CD, and production infrastructure.
Full Stack Developer at Clover
September 1, 2017 - March 1, 2020
Contributed to modernization of enterprise web applications using React.js, TypeScript, and Redux Toolkit. Optimized frontend performance with code splitting, lazy loading, memoization, and state management, achieving reduced page load times and increased user engagement. Built reusable UI components with React 18, React Router, Material UI, and Axios for dashboards and internal tools. Implemented real-time capabilities using WebSockets and Socket.IO for live notifications, activity feeds, and event-driven updates. Developed backend services with Node.js and Express.js, creating RESTful APIs with validation, error handling, and JWT-based authentication integrated with enterprise identity and authorization systems.
