AI Transformation Strategy framework — four pillars for enterprise AI adoption: Strategy (outcome-first roadmaps aligned to business metrics), Integration (API and MCP tool boundaries), Empowerment (self-hosted inference and agent workflows), and Governance (credential-scoped catalogs, segmented trust, and operational sustainability).| Metric | Delivery |
|---|---|
| Scale | 50+ systems unified across 5,500 Walmart and Sam's Club locations |
| Reach | 60,000+ YouTube channels on ViewBooster; millions of channels ingested daily at Zoomin.TV |
| Healthcare | Multi-million-dollar private network engagements — Baxter, Cleveland Clinic, Mayo, Kaiser |
| AI influence | 95%-accurate ML model feedback loop driving Verizon product roadmap |
| Experience | 15+ years — Verizon · Walmart · Zoomin.TV · The Clearing House · Omega IT LLC |
Engineering leader specializing in:
- Enterprise integration & modernization — fragmented legacy estates, API bridges, and P&L-grade data pipelines
- Healthcare & connected care — private networks, device connectivity, and mission-critical resilience for health systems
- Identity & access architecture — SSO federation (SAML/OAuth), segmented trust zones, and credential-scoped service catalogs
- AI & MCP platforms — agent orchestration, local inference, and Model Context Protocol tool layers for enterprise-grade automation
- Distributed systems at scale — inventory automation across thousands of sites, national payment infrastructure, and high-throughput analytics
