Strangler-Fig Modernization of a Healthcare Reporting Service
Overview
What this challenge is about.
Design a strangler-fig router, implement a new .NET 8 service with tests, build a parity harness, and author a 24-week roadmap. Get a verifiable certificate.
The scenario
The hospital network (regulated under GDPR + German hospital information-security law + DiGAV) cannot replatform — too many downstream clinical workflows — but the .NET Framework dependency is reaching end-of-life for security updates.
The Brief
What you'll do, and what you'll demonstrate.
Ship the first strangler-fig extraction of a healthcare reporting service with parity-tests + router + 24-week roadmap.
Earning criteria — what you'll demonstrate
- Design and ship a strangler-fig extraction on a real legacy service
- Build a parity harness that catches behavioral drift
- Roll out via feature-flag canary (5/25/100) safely
- Plan multi-quarter extraction sequencing with regulatory constraints
