About
I've built production LLM and RAG systems for Perplexity AI, Toptal's legal intelligence client, Versana, and Anki. At Perplexity, I developed core RAG, query-routing, MCP, and LangGraph systems supporting Sonar products serving 22M+ monthly active users and 1B+ queries per month.
I've delivered multi-agent legal research platforms with live knowledge graphs, hybrid retrieval, citation grounding, and evaluation harnesses, while improving inference latency, cost governance, and model reliability. My work spans Python, LangGraph, LangChain, MCP, AWS, GCP, FastAPI, Kubernetes, and production MLOps.
Experience
Senior Generative AI Engineer
Designed and built a production-grade multi-agent RAG system for a legal intelligence platform, including real-time document ingestion, a live Neo4j knowledge graph, hybrid retrieval, and a six-agent LangGraph orchestration layer. Implemented evaluation harnesses and production hardening with observability and cost tracking.
