Hire a RAG Systems Engineer in Chicago
I build enterprise Retrieval-Augmented Generation (RAG) pipelines that turn fragmented company documentation into accurate, hallucination-resistant knowledge bases. Utilizing Supabase pgvector, hybrid search, and semantic re-ranking, I deliver high-precision enterprise AI.
Chicago boasts a massive B2B software and logistics tech sector. Building for Chicago enterprises means prioritizing complex data grids, robust user permissions, and utilitarian designs that maximize worker productivity. Working with US and Canadian teams in CST (UTC-6), I overlap enough hours for daily syncs while delivering at rates that make seed-stage budgets go further. Communication is async-first with structured weekly demos.
