The challenge.
- A heavily AI-generated codebase that was chaotic, difficult to maintain, and not production ready.
- A broken payment system with unreliable flows and many unhandled edge cases.
- High user drop-off due to a confusing onboarding journey and poor UX.
- Partially implemented integration with the critical Ornament API, limiting lab result synchronization and analytics.

Our approach.
- Conducted a full codebase audit to identify unstable, AI-generated components and hidden coupling.
- Systematically refactored and restructured the application to create clear, maintainable modules.
- Redesigned the payment architecture with robust error handling, better security, and support for multiple payment models.
- Reimagined onboarding UX with fewer steps, real-time validation, and contextual tooltips to guide the user.
- Completed and hardened the Ornament API integration for reliable lab-result handling.
