Goal: Ensure full order lifecycle management through a robust microservices architecture, covering all involved providers (payment, delivery, inventory, promotions, etc.).

Description: The OMS (Order Management System) team managed 26 Java-based microservices, each dedicated to a specific provider. Services were orchestrated centrally and communicated via JMS and Kafka. An Angular-based back office allowed administrative control. The team did not follow Agile methodologies, and topics were often diverse and technically complex.
