Build and operate low-latency, event-driven microservices end to end (API through storage) using resilience patterns (circuit breakers, retries with jitter, back-pressure, idempotency, sagas/outbox) while contributing to multi-region readiness through sound data partitioning, stateless design, and blast-radius reduction. Implement paved-road patterns for service development, CI/CD, testing, and delivery by contributing to shared libraries, templates, and runbooks while shipping safely via GitOps workflows (e.g., Argo CD/Flux), progressive delivery (canary/blue-green, feature flags), and automated rollback policies.
