Revision of a web service (Java EE, PostgreSQL)

We are in search of a developer to complete the finalization of an ongoing web service project. The backend is developed using Java EE and runs on Weblogic, while the frontend is based on Angular. The application utilizes a PostgreSQL database and occasionally interacts with an Oracle DB.

The primary focus of the tasks will be on the backend, with only rare occasions requiring frontend work. The hourly rate will be provided in the order details. When responding, please include your relevant experience in this field.
