Staff Software Engineer — Product Systems & Regulated Architecture
Healthcare · Insurance · Distributed Enterprise Platforms

I design product systems that remain stable under regulatory constraints, legacy integration, and cross-team complexity. My recent work spans HIPAA-regulated healthcare platforms, large-scale consumer streaming systems, and enterprise modernization initiatives — where architectural decisions directly influence compliance posture, delivery reliability, and long-term operational risk.

Hands-on across mobile and backend systems. Frequently serve as architectural point of contact across product, backend, QA, and security stakeholders.
