Sharepoint & Dropbox API integration, plus later AI

My company, Diligentsia Limited, is developing a B2B data room solution using AI. I am looking for a full stack developer to work on a number of discrete projects on a temporary basis to support the full-time team. Some of the later projects will involve enhancing some of our applications of AI - interesting work! I eish to engage you on a project by project basis to start. I want to use the first projects for you to prove your capabilities.

Our development toolset includes using MERN Stack. Following are the tech stack for each:
● Backend: NodeJS
● Frontend: ReactJS
● Database: MongoDB
● Cloud: AWS
● Code Versioning: Github

The first two projects are as follows (Project Title 1. Data Room Mirroring With Dropbox, and Project Title 2 - Data Room Mirroring With Sharepoint.)
1. You will be familiar with the idea of a set of folders and sub folders containing files, within cloud storage providers Google Drive, Dropbox and Sharepoint.
2. At Diligentsia we have created a folder structure with up to 160 folders and subfolders.
3. We have applied that folder structure to our application, in which users then upload files to those folders in our own Data Repository within our own application - held on our own database.
3. Once loaded into our own Data Repository folders and where the files are stored by us, we give the user the ability to:
a) Choose their cloud storage provider of choice (Drive/Dropbox/Sharepoint.
b) Recreate that folder structure within that cloud storage provider.
c) Upload the files from our Data Repository into the Data Room we have created in the coud provider.
d) Keep both our Data Repository and the cloud provider's Data Room synced.
4. We have already coded, and have working, the mirroring of our Repository into Google Drive.
5. We now wish you to replicate this through enabling the mirroring into Sharepoint and Dropbox.
6. Access will be provided to the code we have successfully used for the Drive mirroring.

Each project involves creating the code to enable us to build out our feature so that the user can choose between Drive, Dropbox and Sharepoint.

We are splitting the project into two; if you successfully complete Project 1, we will engage you for Project 2. If that is successful, we will offer further projects involving AI. We need both projects 1 and 2 to be completed within a week of engagement.

Your previous experience in this field, and particularly integrations using Dropbox and Sharepoint APIs will be a distinct advantage when applying. As would experience of Bard and the Chat GPT API.

The price quoted is for both projects/integrations.
