About

I build platforms where engineering shows up in adoption and throughput — not slide decks. Senior full-stack engineer with 10+ years owning architecture, delivery, and modernization on revenue-critical systems.

At MANIFOLD GROUP (United States · Remote), I have enabled patient intake at national scale for a major U.S. healthcare provider, extended clinical workflows across a national rehabilitation network, and shipped product middleware that keeps fulfillment consistent across web and mobile.

I work best when the outcome is measurable: facilities live, admissions flowing, patients engaged, teams unblocked. That means owning the full stack when needed — APIs, frontends, integrations, and the modernization work that keeps platforms shippable years later.

Independent client work — greenfield products from zero to production — lives in Side projects.

Experience

Outcomes first — what changed, at what scale, and why it mattered.

Senior Software Engineer

MANIFOLD GROUP · United States · Remote

  • Enabled core patient intake at national scale for a major U.S. healthcare provider by architecting and leading a referral & admission platform — deployed at 240+ facilities, 630K+ admissions processed (~30K/month), ~1K monthly users on revenue-critical workflows.
  • Reached 55K+ patients across 80+ hospitals by delivering a cross-platform rehabilitation tracking experience — extending patient engagement and continuity of care nationwide.
  • Standardized post-acute clinical workflows across a national rehabilitation network by extending a FHIR-based care pathways platform — backend services, Angular client, legacy-to-FHIR migration, and production query optimization.
  • Unified ordering and fulfillment behavior across web and mobile for a food-tech client by architecting Shopify-delivery middleware and a shared TypeScript rules engine — reducing duplicated logic and manual routing overhead.
  • Improved reliability and shipping velocity on long-lived enterprise healthcare platforms by driving Angular modernization, state management adoption, and API contract discipline with cross-functional teams.
