PROJECTS

01
CLAIMAI — AI Medical Billing Assistant
Full-stack AI assistant for CPT code classification and medical billing. Architected a RAG pipeline using Hugging Face transformers and Chroma vector database for semantic search over claims knowledge bases. Fine-tuned a domain-specific NLP model managing the full lifecycle from training to production inference. Deployed on Azure Web Apps serving 30 internal users.
