MedFlow Nexus is a full-stack, multi-tenant SaaS platform for medical tourism operations. It centralizes patient management, leads, cases, appointments, medical records, logistics, and finance into one system. I designed and built a scalable architecture using React, Node.js server functions, and Supabase with secure role-based access. The goal is to replace manual workflows with a unified ERP that improves coordination, efficiency, and patient journey tracking for healthcare agencies.
