What I'm looking for

I’m seeking senior engineering roles in health tech to architect cloud-native systems, lead cross-functional teams, and build data-driven products that improve patient outcomes. I value collaborative, compliant, and impact-focused cultures.

I’m a senior software engineer with 8 years designing and scaling mission‑critical healthcare platforms. I design and deliver cloud‑native, HIPAA‑compliant systems that transform complex EHR data into actionable insights — including the Live Tumor Tracker and Unified EHR Fusion Engine that cut reconciliation time by over 50% and improved SLA reliability by 30%.

I lead cross‑functional teams, mentor engineers, and champion engineering best practices like 95% test coverage, CI/CD, and resilient Kubernetes deployments. I’m seeking senior roles where I can architect scalable solutions, accelerate delivery, and bridge technology with care delivery to improve patient outcomes.
