Domain-Driven Design Aggregate Redesign for a Lending API
Overview
What this challenge is about.
Domain-Driven Design Aggregate Redesign for a Lending API. Advanced challenge in design. Designing real products under real constraints, earn a blockchain-ve...
The Brief
What you'll do, and what you'll demonstrate.
Redesign a lending API into proper DDD bounded contexts and aggregates and propose a phased 12-week migration the engineering org can fund.
This is not a design exercise. It is the work a product designer does between a brief and a shipped interface. That distinction matters to every hiring manager who has seen candidates redesign Spotify's homepage and none who have worked under real product 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
- Facilitate an event-storming workshop with non-engineers in the room
- Identify bounded contexts from domain events, not org chart
- Design aggregates that own their invariants
- Build a ubiquitous-language glossary that survives PR review
