Strangler-Fig Modernization of a Healthcare Reporting Service
Overview
What this challenge is about.
Audit the report categories (around 14) and pick operating-theater utilization for the pilot extraction (high volume, moderate complexity, low regulatory blast-radius). Design the strangler-fig: a router service that forwards each report request to either legacy or new based on report type + feature flag. Implement the new .NET 8 service with the 9 report templates in scope, full unit + integration tests, and a parity harness that runs old + new on the same input and diff-compares outputs nightly. Run parity in shadow-mode for 2 weeks before flipping the flag to 5 percent → 25 percent → 100 percent. Author a 24-week roadmap extracting the remaining 13 categories. Deliver design, new service, router, parity harness + report, and roadmap.
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
