Capstone journey

One app · 14 guided projects · Beginner to Expert

Inherit one real system in production, a storefront checkout, and make it provably reliable, from your first pager to gating launches.

You take the same app (Carta) through 14 projects, each one solving the pain the last left behind. By the end you have shipped a system with defined SLOs, symptom alerts, contained failures, tested capacity, and a reliability practice around it, the kind of portfolio piece that gets interviews.
