Private knowledge platform

BrainVault

Built a personal knowledge system for ingestion, organization, semantic search, and retrieval, with the local vault as source of truth and a fail-closed privacy domain. Authored and deployed an 11-tool remote MCP server on Supabase Edge Functions, secured with OAuth 2.1 and database row-level security.
