— Modernizing a Patient Data Tracking App for German Healthcare

Cross-platform HealthTech app modernization using .NET MAUI

Project Overview: Future-Proofing Patient-Centered Mobile Apps

A German healthcare company referred to our partner’s assistance to revitalize their legacy mobile app, originally built with Xamarin, used by clinicians and caregivers to track critical patient medical data. The app plays a vital role in day-to-day care operations by capturing data such as:

  • Patient care plans
  • Vital signs
  • Wound status
  • Pain levels
  • Medical test results

However, the existing codebase had become outdated and was facing compatibility issues across modern devices.

Objectives

  • Fix deprecated Xamarin code
  • Optimize performance and eliminate bugs
  • Add new features based on evolving clinical needs
  • Prepare for seamless migration to .NET MAUI
  • Improve app stability, speed, and user experience

Team & Execution

  • Team: 1 Senior Developer
  • Tech Stack: Xamarin (Cross-platform), preparing for migration to .NET MAUI
  • Close collaboration with internal QA and clinical product teams

Delivered Outcomes

🔶 Codebase Modernization

  • Rewrote legacy, deprecated components to align with modern standards
  • Improved compatibility with iOS and Android updates

🔶 Performance Boost

  • Achieved smoother load times and responsive UI
  • Enhanced app reliability and uptime

🔶 Bug Elimination

  • Performed extensive debugging and resolved major pain points reported by users
  • Increased user satisfaction and reduced support tickets

🔶 Feature Expansion

  • Added new capabilities for tracking pain assessments and test result visuals
  • Enhanced patient data entry and retrieval features

🔶 Migration Strategy to .NET MAUI

  • Created a scalable plan to migrate from Xamarin to .NET MAUI before Xamarin’s official sunset
  • Future-proofed the app for long-term maintainability

Results & Value

  • Improved clinician efficiency with faster, more stable mobile workflows
  • Reduced tech debt through strategic modernization
  • Ensured continued compliance and performance in a regulated healthcare environment
  • Enabled adaptability for new features and future platform upgrades
