A copilot that
shows its work
to a human.

Built RCM copilot, payer-policy intelligence, medical-necessity support, and document-extraction capabilities using Amazon Bedrock and Gemini. Bring source evidence into a workflow with human review and sensitive-data safeguards.

Source-oriented policy and document support with a human reviewer in the workflow. Product figure uses illustrative data.

Boring tools,
sharp edges.

I pick tools a team can run at 3 a.m. Aurora before a new database, a queue before a framework, a metric before a guess. The craft is in how they fit together, and in the audit log that proves it.
