What I'm looking for

I seek roles building scalable, event-driven platforms and AI workflows in collaborative, regulated environments where I can mentor engineers and shape architecture.

I am a Staff Software Engineer with 10+ years architecting distributed systems, event-driven platforms, and real-time data pipelines for large-scale Healthcare and consumer applications. I deliver high-scale microservices, AI-driven workflows, and clinician-facing tools while raising engineering standards and reducing system complexity.

At Humana I led the Remote Patient Monitoring platform, architecting multi-AZ infrastructure, event-driven backends, and an AI-powered triage engine that scaled to millions of clinical events per day while improving uptime and reducing costs. I mentor engineers, collaborate with clinicians and product teams, and drive cross-team technical decisions in regulated, high-impact environments.
