I've built production AI platforms at Databackfill and Salesforce, delivering multi-agent workflows, RAG systems, model-routing services, and data pipelines used by tens of thousands of B2B users.

At Databackfill, I built LangGraph and LlamaIndex agent workflows, a Pinecone and pgvector RAG stack, and evaluation harnesses for prompt and agent changes. My work improved retrieval accuracy by 35%, reduced monthly LLM spend by about 30%, and brought cache-hit p95 latency below 150 ms.

I led three engineers, mentored junior developers, owned AI-platform on-call operations, and created runbooks for model and retrieval failures.

At Salesforce, I built real-time ML scoring services and event-driven data platforms processing more than 2 million daily records, improving sales-team throughput by roughly 30%. Earlier at Wise Health System, I shipped internal web applications and automation that reduced support ticket volume for 500+ staff by 60%.
