Overview
What this challenge is about.
Design an Anti-Corruption Layer for a Legacy Hospital EHR. Advanced challenge in code. Writing production code that solves real engineering problems, earn a ...
The Brief
What you'll do, and what you'll demonstrate.
Design and prototype an Anti-Corruption Layer translating a legacy HL7 v2 EHR feed into a clean domain model the modern care-coordination platform can build on safely.
This is not a coding exercise. It is the work a software engineer does between a Jira ticket and a merged PR. That distinction matters to every hiring manager who has seen candidates solve LeetCode problems and none who have shipped production code under real constraints.
When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."
Earning criteria — what you'll demonstrate
- Design an Anti-Corruption Layer protecting a clean domain from legacy contamination
- Translate legacy data models without leaking their concepts into the new design
- Apply property-based testing to translation correctness
- Document translation rules in a form ops + clinical staff can audit
