By optimizing batch processing, prompts, and models, I reduced AI inference costs by 50%. At Newfire Global Partners, I directed a team of 8 engineers through a complex legacy-to-cloud migration and architected a healthcare revenue-cycle workflow covering 837 claims, 835 remittance, and related acknowledgment processes. At SutureHealth, I built a production AI-assisted development toolkit with healthcare-safe review agents and accelerated .NET and EF Core migration analysis from months to 3 days. I’m interested in Principal- or Staff-level roles where I can shape architecture, lead engineering teams, and apply cloud and AI technologies to challenging problems. ``` ## Experience ### Senior Software Engineer SutureHealth.
