application programming interface

I am looking to hire a freelancer experienced in application programming interface (API) development. I have specific functionality requirements, that must be met in less than 1 month. The successful freelancer can anticipate a fair payment for meeting the requirements within the allocated timeline. If you have the relevant experience and skills to complete this project, please get in touch.
