What I'm looking for

I'm looking to build secure, observable production AI systems, leading teams and turning LLM, RAG, and agentic AI prototypes into high-impact products.

At Apple, I build enterprise GenAI platform capabilities for knowledge assistants, AI productivity applications, and intelligent workflow automation. I develop production LLM, RAG, and agentic systems in Python, helping teams integrate secure AI capabilities into their products.

I’ve built RAG infrastructure with LlamaIndex and Pinecone, agent workflows with LangChain and LangGraph, and unified model access across OpenAI, Anthropic, and AWS Bedrock. I improved LLM inference cost by 30% and expanded automated evaluation coverage to more than 100 scenarios before release.

Earlier at Apple and Intel, I built shared ML platforms, model-serving systems, semantic search, data pipelines, and performance-prediction tools. I also lead technical planning, mentor engineers, and move AI systems from prototype to observable production.
