• Architected and built a multi-tenant healthcare scheduling platform from scratch using Next.js 16 (App Router), TypeScript (strict mode), Supabase (PostgreSQL), and Tailwind CSS.
• Engineered tenant isolation and granular RBAC using stateless JWT middleware (jose) and Row-Level Security (RLS) policies on PostgreSQL, incorporating audit logging for HIPAA-oriented compliance.
• Designed an AI scheduling platform on Model Context Protocol (MCP) with a typed tool registry serving a WhatsApp booking bot, dashboard assistant, and patient chat widget with Redis state management and Upstash rate limiting.
• Integrated full-stack subscription infrastructure using Stripe (checkouts, webhooks, portal, server-side usage gating) and third-party systems including Google Calendar two-way sync, Twilio SMS/WhatsApp, Resend, and Vercel AI Gateway.
• Implemented rigorous engineering quality standards with TDD using Playwright for E2E testing, Vitest for unit coverage, automated accessibility checks, and containerized local/production parity using Docker Compose.

Genkō is the EMR and scheduling platform for small and multi-location practices: one record from the booking to the signed note.
- Conflict-free scheduling: no double-bookings, whether staff or the patient portal books
- Signed notes that lock for everyone. Corrections are signed addenda, and nothing is quietly edited or deleted
- ICD-10-CM problem list, allergies, medications and vitals
- 42 specialty templates in 11 groups: dental, physiotherapy, chiropractic, mental health, optometry, veterinary, aesthetics, nutrition, speech and OT, wound care
- Patient portal with self-service booking, pre-visit intake forms and shared visit summaries
- WhatsApp reminders patients can reply to: confirm, reschedule, cancel
- Patient documents, full record download, audit logs and retention you set
- Multi-location management from one login
- REST API and MCP server for AI agents, with scoped keys
- English and Spanish
