Rebuilding a healthcare platform from fragile codebase to market-ready product.
A three-phase stabilization, subscription build, and cross-platform rebuild that moved a fragile inherited codebase to a stable, tested, and market-ready product with iOS and Android support delivered within a one-month subscription MVP window.
THE CHALLENGE
A digital health company delivering personalized treatments through mobile and web platforms inherited a fragile codebase after a development partner change. There was no automated testing, minimal documentation, and an unstable release process where fixing one issue consistently introduced others. Simultaneously, the business needed to launch a subscription and CRM onboarding system and expand from iOS-only to full cross-platform support, neither of which was achievable on the existing foundation.
OUR APPROACH
The audit had to come before anything else. Moving directly to feature development on an unstable codebase would have compounded the existing problems rather than resolved them. We needed to understand the true state of the system, including where the risk was concentrated and what the remediation sequence should be, before committing to any development work. That discipline was the difference between fixing the platform and continuing to firefight it.
We chose to sequence the three phases deliberately: stabilize first, then build the subscription system the business needed to generate revenue, then rebuild the application on a framework that could support both platforms without carrying the original codebase forward. Each phase created the conditions the next one required, which meant the work compounded rather than accumulated.
- • Conducting a comprehensive technical audit across frontend, backend, and infrastructure to produce a risk-scored remediation roadmap before any development work began.
- • Designing and executing over 100 automated test cases and introducing tiered staging environments to establish a stable, releasable product state.
- • Building a fully integrated subscription and CRM onboarding system including Stripe payment processing, Zoho CRM synchronization, and a patient self-service web portal.
- • Migrating the patient application from React Native to Flutter to achieve native cross-platform support on iOS and Android within a single maintainable codebase.
THE RESULTS
Subscription MVP shipped in one month.
The full patient onboarding workflow including payment integration, CRM syncing, and terms acceptance was designed and shipped within a one-month window, unlocking a revenue stream the business had been unable to launch.
Cross-platform app live on iOS and Android.
The patient application was rebuilt in Flutter and deployed on both platforms, removing the iOS-only ceiling on patient acquisition that had constrained the business since launch.
Release process stabilized and automated.
Automated testing across more than 100 test cases and tiered staging environments replaced a manual, error-prone release cycle, allowing the team to ship updates with confidence rather than apprehension.
Development model shifted from reactive to proactive.
Leadership regained control of the product roadmap, replacing emergency fixes with a planned development cycle backed by documentation, automated quality gates, and a foundation ready for future features.
As the platform moves into its next phase, including patient video features and LMS integration, it does so on a foundation that was built to support that growth rather than one that will need to be replaced before it can. The value of the stabilization and rebuild work compounds with every feature that follows, which is what makes this engagement significant beyond its immediate deliverables.
