Built and maintained Node.js/Express streaming services that ingest a live hardware video encoder feed and publish it into Amazon Chime SDK rooms for remote clinicians, enabling real-time ultrasound sound screen output in the React client. Developed and scaled a multi-tenant Sonosync console and platform capable of deploying the full Sonosync system to any AWS region, sized by user and device needs. Worked on backend services with authentication and realtime capabilities, including React/TypeScript/AWS Lambda and DynamoDB-based APIs, and contributed to Sonosync Spring Boot backend work. Dockerized services, load-tested streaming workloads to handle 96 concurrent streams, and supported AWS deployment on EC2/ECS/S3/Lambda with CI/CD practices. Also shipped production features like an AI bowel-assist workflow using EfficientDet-D1 and SegFormer models, and extended SmartThings AVPlay media playback with RTSP/WebRTC camera streaming.

Developed a bookstore management system using Spring Boot, Java Persistence API, AngularJS, and MySQL. Built and integrated features such as catalog and order flows, and implemented REST-style controllers and service layers. Completed multiple full-stack projects including a tutoring hub backend and React client with JWT-protected controller/service/repository layers, and a data extraction/textile ERP API project using Node.js, Express, JWT auth, and React Express APIs with normalized Oracle schemas for SKUs, consignments, catalogues, and staff. Also implemented a real-time Node/Express/Socket.IO chat application with room-based messaging and live member updates.
