John Holstein
AI Technical Product Architect — Novant Health
Candidate Brief — Prepared for TEKsystems
Recruiter: Darbee Kramer
April 28, 2026
AI architect with production deployments specifically in the clinical, operational, and regulatory domains that define Novant Health’s Institute for Innovation — zero production failures across five AI systems in eight years of regulated healthcare work.
Why This Candidate for This Role
Healthcare AI in production — covers both open positions.
Revenue Cycle: Evernorth (value-based care, 147 CMS KPIs standardized) and Optum (Medicaid/TPA analytics, unified Snowflake source). Clinical: Invistics (drug diversion ML deployed to 300+ U.S. hospitals, 96% detection accuracy) and Optinosis (early cancer detection, active production with paying customers).
Agentic AI and RAG — deployed systems, not pilot projects.
Multi-agent GenAI at Amgen cut FDA regulatory submission cycle time 40% and expanded scope after first production milestone triggered Board approval. Agentic evaluation pipeline at NewsRx governs clinical biomedical content quality at scale.
Responsible AI embedded in every deployment.
HIPAA, GxP, and Human-in-the-Loop governance across every healthcare system. FDA-submission GenAI required GxP change control. The governance is the practice, not the objective.
Owns the full execution stack.
Sole contributor at NewsRx against a four-person staffing plan, delivering infrastructure beyond contracted scope. Product Owner at Amgen when the prior PO was promoted mid-project. Architecture through delivery — not advisory only.
What Makes This Candidate Different
Most AI architects have cloud credentials. Few have shipped AI into regulated clinical environments and kept it running. Zero production failures across five systems in eight years.
Healthcare governance is a lived operational constraint — not a slide deck credential. NRC, FDA, HIPAA, GxP, EU MDR have all been active production conditions.
Covers both open positions. The Revenue Cycle hire and the Clinical hire require different backgrounds for most applicants. Not here.
Functions as Solutions Architect and Principal Engineer. The JD specifically requires both. Most candidates are one or the other.
Lean-team multiplier. Consistently delivers at multiples of traditional team capacity: 4-person scope solo, 23-person legacy rebuilt with 3.
