Integrate data from multiple marketplace

I am looking for a freelancer to help me integrate sales data from multiple marketplaces in Indonesia (Tokopedia, Shopee, Blibli etc) into one central database. Specifically, I want to integrate data from marketplaces not mentioned on the initial list, which are yet to be specified. More specifically, I would like the freelancer to help me integrate sales data from the specified marketplaces, such as how much profit was made each day. Lastly, I need the data to be updated and integrated on a weekly basis.

I need a freelancer who is experienced with back-end development, as well as data warehousing and integration. The freelancer will need to have extensive knowledge on the technologies used to integrate and sync data among multiple third-party marketplaces. They will also be responsible for developing the necessary scripts and code to ensure that the data is synced on time and correctly between the marketplaces.

If you have the skills and experience necessary to complete this project, then I have the perfect job for you! Thank you for your time!
