iOS developer behind OpenIntelligence, an on-device agentic retrieval app that runs beyond Apple's 4,096-token limit.

I built OpenIntelligence, an on-device agentic retrieval engine that runs fully offline and is now on version 5.5 with paying users. Its retrieval pipeline combines hybrid search, reranking, and verification gates, and its recursive reasoning loop goes beyond Apple's 4,096-token on-device limit.

At Stryker, I provide intraoperative technical support for surgical teams at VA Palo Alto across eight operating rooms. I also shipped OpenResponses and developed OpenClinic as a prototype; across my work, I test real inputs and failure modes, and make the system say when it can't answer with grounding.
