Case study
Scaling Patient Triage with LLMs
To address growing triage volume in patient chat messages, I designed and deployed an AI-driven system using Claude LLM via Amazon Bedrock. It classified message category and severity, responded safely to low-risk inquiries, and escalated urgent messages to providers with real-time SMS alerts.
Case study
Launching a Scalable, HIPAA-Compliant Virtual Care Platform
A healthcare startup set out to deliver virtual medical care via mobile and web applications but needed a technical foundation in place. They needed a scalable, compliant infrastructure and a product launched quickly to validate their market.
Thiago was instrumental in defining and building Caraway's technology platform. He defined the v1 stack, built our mobile and provider applications, designed and managed a complex architecture with numerous integrations, and launched our MVP on time and on budget against extremely challenging timelines.
