Have you led the end-to-end architecture of a web product spanning a Rails backend and a modern FE (Svelte/Vue/React)?✱

Have you implemented reliability patterns such as idempotency, retries, circuit breakers, and defined SLO/SLA metrics?✱

Have you planned and executed zero-downtime migrations and staged rollouts (canaries/feature flags) at scale?✱

Have you mentored senior engineers and set cross-team engineering standards (testing strategy, design system, performance/accessibility)?✱

Are you comfortable making framework-agnostic FE decisions and reviewing FE architecture for quality and performance?✱
