Technology constraints drive automation

" summary

Shopify standardizes on Rails + React + GraphQL, a monolith that enforces constraints to drive automation and quality. Company tools include services_db (service checks like Ruby version and on‑call), dev (one‑hour local setup, dev up/server/tests) and ship and mobile (three people build it in three months, rolled out to every app in nine months). Results: ~40 deploys/day, ~50‑minute deploys, ~140k tests reduced to <100k with selective execution and 83% developer satisfaction.
