- Technologies used: Python, AppScripts, LangSmith - Developed automation scripts and API integrations, including documentation, to reduce manual data entry and streamline ingestion workflows, resulting in up to a 60% reduction in data entry time. - Collaborated with prompt‑engineering and product teams to refine prompt templates and guardrail definitions, establishing a standardized prompt library and response‑validation procedures for model interactions. - Enhanced an existing LLM-based agent to support file ingestion and structured output: built a multi-agent system that indexes large document repositories by generating searchable summaries, then answers questions by searching source files and extracting quotes with page numbers.
