About the project

I designed and built VaultMind's ingestion and retrieval pipeline to bring repositories, workspace tools, drive files, and authored documents into one searchable index. Its backend combines PostgreSQL and pgvector with scoped retrieval, source citations, and responses that decline when evidence is insufficient. The self-hosted application serves both a conversational interface and read-only MCP tools for coding agents.
