Project context: Development of a transport ETA (Estimated Time of Arrival) calculation application for factory to warehouse deliveries. Creation of micro-services calculating dates by applying a strategy pattern. Applications are orchestrated using Kubernetes. Use of Kafka or REST API depending on the entry point. The application is based on Java 23 with reactive programming (Reactor project).

Mission:

• Development and participation in the design of the application in Java 23 (Spring Boot 3) and reactive programming

• Regular pair programming and systematic Pull Requests

• Creation of unit tests (JUnit) and integration tests (Cucumber)

• Participation in writing requirements and specifications, in collaboration with POs / functional support

• Estimation of the workload required for development

• Guarantee of the quality of deliverables: SonarCloud analysis OK, optimization of the number of executed queries, memory/CPU consumption, …

• Implementation of comprehensive monitoring using the Datadog tool

• Regular agile rituals

• Daily Meeting

• Backlog refinement (planning poker)

• Sprint review (demos)
