I am looking for an experienced java back-end developer to create a powerful and efficient application. The developer is expected to develop the required APIs from scratch within 1-2 weeks, with user authentication and authorization, database management, and API integration. They should be well-versed in developing secure and robust back-end solutions with an emphasis on scalability and maintainability. The developer should also have experience in coding for multi-tenancy and coding best practices, as well as being able to communicate and collaborate effectively with team members throughout the duration of the project.
