AI Engineer - Piper Sandler
Developed LLM-powered internal research tools using Retrieval-Augmented Generation (RAG) to support analyst workflows across sentiment, macroeconomic, and fundamental research. Improved LLM response quality through prompt engineering, document chunking strategies, and embedding-based retrieval for more relevant and consistent insights. Collaborated with ML and backend engineers to integrate LLM services via REST APIs and support scalable pipelines, model evaluation, and continuous performance improvements. • Built RAG workflows with LangChain and Pinecone/FAISS for contextual research and Q&A. • Designed agent-style task orchestration and context management for multi-step analytical processes. • Integrated LLM service endpoints and supported iterative model evaluation and tuning. • Implemented retrieval and prompt strategies to enhance relevance, consistency, and output quality.
