The company & platform behind every pharmacy app below. RevealSite is a software and digital-marketing company that works exclusively with independent and community pharmacies — effectively their outsourced digital department. It runs a multi-tenant, white-label engagement platform: a new pharmacy spins up by client_id with its own branding, hours and storefront, and patients get prescription refills, transfers, appointment booking, medication reminders and two-way messaging — each request auto-routed to the pharmacy by fax & email. This is where I worked, building and shipping the Flutter patient apps (J&D, Quick Rx, Holland, Medical Compounding and more) on top of this one shared platform.
