Cosee GmbH · 2022 to 2023
Java Backend Developer · Integration work
Feature development and maintenance of a backend service integrating digital marketplaces, focused on robust interfaces, persistence and deployment.
Technology map
The focus was adapter logic, stable interfaces, persistence, data migrations and maintainable evolution. A central part was a domain-specific mapping DSL based on JsonPath, making stakeholder domain rules expressible and processable in the service. Automated tests and containerized delivery in a platform environment were part of the work.
