The Brief
What you'll do, and what you'll demonstrate.
Recommend monolith vs modular monolith vs microservices for a 50-person engineering org with evidence from the codebase, team topology, and scaling pressures.
This is not a case study exercise. It is the work a consultant does when a client needs a recommendation backed by evidence. That distinction matters to every hiring manager who has seen candidates recite Porter's Five Forces and none who have built a recommendation a client would actually pay for.
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 git co-change analysis to find bounded contexts in a Rails monolith
- Apply Team Topologies (Stream-aligned, Platform, Enabling, Complicated-Subsystem) to architecture decisions
- Compare microservices vs modular monolith vs status quo with evidence
- Write a decision memo that survives engineering scrutiny and gets sign-off
