When GraphRAG is worth it
Only move to GraphRAG when the answer depends on relationships that plain RAG retrieval alone cannot preserve.

Senior ML engineer building reliable AI systems for decision-critical work
Bio
I build AI and machine learning systems for messy, high-stakes problems. I’m especially interested in Bayesian modeling, decision-making under uncertainty, and systems that use real domain knowledge instead of pretending every problem is just next-token prediction. Most of my work lives in the gap between research ideas and production systems that need to be reliable, interpretable, and worth trusting.
