WORK HISTORY
Data Scientist Machine Learning, Llm & Rag Systems Python, Sql, Aws @7technix Llc
US
Designed and deployed a RAG chatbot using Python, LangChain, ChromaDB, and HuggingFace embeddings, partnering with cross-functional teams and articulating retrieval behavior to enhance semantic search and lift query success rate by 15%. Re-engineered retrieval pipelines with engineering and knowledge teams, slashing document lookup time from 6.2 to 3.9 minutes by optimizing embeddings, tuning retrievers, and refining context selection. Operationalized the system using Docker and AWS (EC2/S3), driving team adoption and transforming daily workflows—reducing internal search effort by ~90 employee hours per month.
