Senior Product Engineer — multi-tenant SaaS, operational platforms, and production migrations.
I build systems where multiple roles, permissions, and real-world workflows have to work together — not just demo well.
Most flagship code is private. I publish architecture case studies instead of dumping client repos.

Multi-role healthcare SaaS for rep–practice appointment coordination. Moved the platform from fragile hosting and incomplete workflows to MVP-ready production software — guided booking, role-based dashboards, Cal.com integration, and Oracle → Vercel/Railway migration.

A lot of my strongest work lives in private or client repositories. When I cannot share code, I write case studies that explain the product, architecture, boundaries, and tradeoffs — the same material I'd walk a staff engineer through in a design review.
Previously managed technical delivery for ~50 consultants across an ~$8M services portfolio at Enhance IT — useful context for how I think about execution, not just implementation.
