This sequence diagram is used to map the checkout path from customer submission through cart validation, card charging, failure handling, inventory reservation, and receipt delivery. It helps teams verify order of operations, error recovery with a retry screen after a failed charge, and service dependencies between Checkout, Payment Gateway, Inventory Service, and Email Service. Product managers, engineers, QA analysts, and solution architects would use it.

A sequence diagram for a CI/CD pipeline where a GitHub commit triggers the build server, which builds and tests the application, pushes a Docker image to the registry, deploys it to staging for verification, and then promotes it to production. It is used to clarify deployment order, handoffs, and acknowledgements, helping teams validate release flow, spot bottlenecks, and align automation. DevOps engineers, platform teams, and developers would use it.

A sequence diagram for a Kafka producer-consumer flow with offset commit, mapping how a Producer publishes a record to a Kafka Broker, how a Consumer Group polls and processes the returned batch, and how offsets are committed to an Offset Store with acknowledgment. It is used to clarify delivery and consumption order, support debugging of acknowledgment and offset handling, and help backend engineers, data platform teams, and architects design reliable event-driven systems.
