Description
Our CQRS + Event Sourcing System Design service provides a robust architectural framework where read and write operations are segregated (CQRS) and every change to the system state is captured as a sequence of events (event sourcing). This design pattern ensures data immutability, traceability, and supports features like time travel, audit logs, and snapshotting. The system allows optimized read models tailored to application requirements while ensuring command models remain consistent and secure. We implement this using frameworks such as Axon (Java), MediatR (C#), or custom setups with Kafka, PostgreSQL (with WAL logs), and event stores. Use cases include financial transactions, supply chain workflows, booking systems, and domains requiring strong auditability. The service includes domain modeling (DDD), write/read model separation, eventual consistency handling, and sagas for distributed transactions. By adopting CQRS + Event Sourcing, organizations gain improved system performance, strong historical data recovery, and compliance-ready architectures for regulated industries.
