If you want to create a well designed Django Restful API based on a legacy database that you or your company already have, you could hire me. You will get a beatiful and performant API in about 10 hours of work.
I am only available on weekends for doing the job but we could exchange emails over the week in order to understand your requirements.
I will also include swagger documentation about the API so your developers or clients can use it without looking at the backend code.
