From a one-star app to a platform
A PE-backed healthcare credentialing company runs access control for hospitals nationwide — 100,000+ medical device and pharma reps credentialed, badged, and checked in at hospital doors. The product worked. The technology didn't: a 20-year-old server-rendered web app, and a mobile "app" that was the website in a webview — rated 1.0 on Google Play, with no iPhone version at all. We rebuilt the experience and the architecture underneath it.
A good business trapped in old technology
The domain is demanding: hospitals require every visiting sales rep to be credentialed — background checks, policies, certifications — before entering. Reps check in at kiosks with QR codes and badges; subscriptions gate access; compliance is continuous. The company had won this market with a platform built two decades ago. Three forces made "keep patching it" impossible.
1 · The users had voted
The mobile app was the website wrapped in a webview — slow, awkward, and unloved. A 1.0 rating on Google Play, and no iOS app at all, for a product whose primary users live on their phones between hospital visits.
2 · The owner had plans
The PE firm behind the company was acquiring complementary businesses that needed to integrate. A 20-year-old server-rendered monolith had no clean way to let anything connect.
3 · The vision had changed
A new CTO arrived with a platform vision: the product shouldn't just have an app — it should expose its capabilities so acquisitions, partners, and future products could build on them.
Star visual illustrative — the 1.0 "before" rating is the real, painful number.
New front doors, and a backend that finally has an API
The rebuild ran on two tracks: a React Native mobile-first experience (plus modern web) for every persona, and a backend transformed from page-renderer into an API platform.
Mobile-first, because the users are
A rep's real workflow happens in parking lots and lobbies: check what's expiring, upload a document, pull up the QR code at the kiosk. The new app is designed around those moments — not a desktop site squeezed into a phone.
Two decades of domain logic, kept
The rebuild honored what made the product win: credential packets per hospital's rules, subscription gating, kiosk scan flows, multi-tenant operation. We modernized the delivery, not the hard-earned business rules.
Designed for the roadmap, not just the release
The API surface is the PE thesis made technical: every acquired company that needs to integrate now has a front door instead of a fork of the codebase.
Every solution has its own story

Modernization isn't a rewrite for its own sake. It's giving a proven business the technology its next decade requires — without breaking the decade that got it here.Why the domain engine survived and the webview didn't
