About this gig

If you're working with connected data, Neo4j is powerful, but only when the model and queries are right. I'm a Neo4j Certified Professional and have built on Neo4j since 2018, including a membership and leadership system for 5,000+ members across 1,000+ sites, community knowledge graphs, and GraphRAG chatbots that answer with their sources.


I can help you:

  • Design or redesign your graph model
  • Find and fix slow Cypher queries
  • Debug wrong or missing results
  • Set up GraphRAG: an AI that answers questions from your graph and shows its sources
  • Connect Neo4j to your app through GraphQL or an API

I don't just write Cypher. I help you think in graphs.


Send me your schema or the query that's giving you trouble, and I'll tell you what I'd change before you order.

I build AI agents, voice agents and document automation for teams buried in manual work, with past delivery for clients like Uber, McDonald's and AirWick. ✔ A document AI system processing 1.5M documents a month: a two-week job now takes under three minutes ✔ An AI agent that answered 314 leads in 13 days, each in under a minute ✔ Neo4j knowledge graphs and GraphRAG search where every answer shows its source 👋 I'm JD, a full-stack developer and AI expert with 8 years' experience delivering fast, scalable software that just works. I'd love to help you do the same.
