Overview
What this challenge is about.
CI/CD Pipeline for a SaaS Monorepo with 14 Services. Intermediate challenge in code. Writing production code that solves real engineering problems, earn a bl...
The Brief
What you'll do, and what you'll demonstrate.
Cut monorepo CI from 47 minutes to under 12 minutes commit-to-deploy with affected-only builds + tests across 14 services.
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
- Use a monorepo build tool's affected-graph to skip unaffected work
- Configure remote build cache that is shared across CI and developer machines
- Parallelize CI jobs with matrix strategies bounded by runner concurrency
- Diagnose cache-miss spikes and adjust hashing inputs accordingly
