In a micro-services oriented architecture, I was able to participate in the integration of new cash register software (POS).

○ In the first phase, it was necessary to industrialize the production of new integrations. Each integration was based on a template, containing a set of integration tests to ensure the consistency of data retrieved from each POS. An abstraction layer then standardizes the data for use in other parts of the solution.

○ In the second phase, I participated in the integration of new POS into the solution. The API solutions offered by third-party editors are very diverse and their integration into a common format is not always easy.

○ Finally, in the last part of the mission, I joined the team in charge of the POS virtualization layer to contribute to the enrichment of the component, in a necessary reorganization effort to improve resilience and maintainability.
