Meridian

Join a multi-tenant claims platform as its third engineer and ship ten sprints of real tickets - contracts, money, tenants, delivery, deployment, and the agent's own PRs included.

Checking your progress

10 sprints - 50 tickets - ~58 h - Mid to Senior

How it is graded

VisibleThe definition of done on the ticket.
HiddenThe edge cases a careful engineer would have thought of.
RegressionEvery earlier sprint's suite.
AdversaryA hostile actor runs against your implementation.

Scored on escaped defect rate: the share of hidden checks that get past you. It goes down over the arc, and that curve is the artifact.

What you'll be able to do

Sprint 1: Contracts

Sprint 2: Money & Time

Sprint 3: Tenants: make the database refuse

Sprint 4: Delivery: Pay It Once

Sprint 5: Parity: Works on My Machine

Sprint 6: Ship it

Sprint 7: When It Breaks

Sprint 8: The model

Sprint 9: Trust it

Sprint 10: The Agent's PR
