Production RAG Assistant
Self-hosted knowledge base that puts expert know-how in front of users around the clock.
Problem
Relying on OpenAI as the vector store tied critical answers to a third party and blocked full control over proprietary expertise.
Role
Architect & sole backend engineer
Stack
Elixir, Phoenix LiveView, PostgreSQL, pgvector, OpenAI / Gemini
Result
Decoupled embeddings and retrieval to on-prem servers with pgvector, delivering 24/7 expert Q&A with citations, rate limits, and multi-channel access.
