Scaling R&D to thousands of people without dedicated QA
summary
Shopify scales R&D to thousands without a dedicated QA by making developers own changes end-to-end, running ~800 deploys per day companywide (about 40 to core), and serving 83,000 requests/sec for 800,000 merchants. Concrete tooling enables this: local env tooling dev plus dev top-hat for exact test snapshots, an orchestrator ship it that merges and rolls out via 5% canaries, and Slack ops via spy with deploy dashboards.
