Contacts

This is Joel's personal contact management system that ties into his actual Vault directory. It maintains markdown files with structured frontmatter for everyone in his network, from egghead instructors to collaborators. The interesting bit is the enrichment pipeline: fire an Inngest event and it fans out across seven sources (Slack, his old Roam archive, GitHub, recall memory, Typesense) and synthesizes a full dossier in about 60 seconds for five cents. VIP contacts get the deep treatment with ongoing monitoring via Google Alerts and social feeds. If you're building your own second brain or CRM and want to see how someone wires up multi-source intelligence gathering with actual cost and latency numbers, the source is worth reading through.
