Mason G.
AI Developer | RAG Chatbots, PDF Search & OpenAI Apps
I build AI tools that answer questions from PDFs, internal documents, and company knowledge bases with citations. I can help you build RAG chatbots, PDF Q&A tools, OpenAI integrations, document search systems, structured extraction pipelines, and AI backend APIs. Recent work includes SpecFinder, a construction PDF search and cited-answer tool for long technical documents, and Voices That Remain, a public archive with an AI pipeline for transcription, metadata extraction, entity resolution, and human review. My focus is practical document AI: reliable retrieval, page-level citations, source evidence, clear uncertainty, and systems that work beyond a demo. Tech: Python, TypeScript, React, Node.js, OpenAI API, PostgreSQL, Supabase, vector/hybrid retrieval, and Google Cloud.
