Overview
What this challenge is about.
Event-Driven Architecture for an Order-to-Cash Pipeline. Advanced challenge in design. Designing real products under real constraints, earn a blockchain-veri...
The Brief
What you'll do, and what you'll demonstrate.
Design an event-driven order-to-cash architecture with explicit choreography, schema evolution, and 5 named failure-mode mitigations.
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
- Design event-driven architectures with choreography vs orchestration trade-offs
- Specify Avro schemas with forward/backward-compatible evolution rules
- Apply saga patterns for distributed transactions with compensating actions
- Document architecture decisions with ADRs that survive team turnover
