About the Client
Industry
Healthcare
Company Size
200 to 350 staff across clinics
Background
A regional provider network serving thousands of patients monthly. Their existing experience relied on calls and email, creating scheduling delays, missed appointments, and limited engagement.
Challenges We Solved
Scheduling friction and missed appointments
Patients could not easily reschedule or receive timely reminders, contributing to avoidable no shows.
Secure messaging requirements
The client needed encrypted messaging with clear access control and audit friendly behavior.
Unreliable connectivity
Patients often used the app on poor networks, so critical actions needed resilient sync behavior.
Fast iteration after launch
The team required a release pipeline that supported frequent updates and quick fixes.
The Mission
Deliver a secure patient app that improves scheduling and engagement, supports reliable messaging, and remains stable under real world connectivity.

How We Fixed It
Secure auth and session reliability
Hardened token refresh handling and added retry and backoff behavior to keep sessions stable under network variation.
Messaging and scheduling UX improvements
Optimized flows for reminders, rescheduling, and message triage with clear states and confirmations.
Release engineering
Established a repeatable build and release process with staged rollouts and monitoring alerts.
Measurable Outcomes
The mobile app reduced scheduling burden on staff and improved patient engagement with reliable access to appointments and communication.
