Fix and develop Depop Bot

Hello,

I have a bot for Depop. I have worked with multiple previous developers and it is about 80 % complete. Its written in TypeScript, and the bot itself is a an app on a website.
It uses Docker to deploy and depends on Redis and Postgres. It has features such as following users, unfollowing users, liking pictures. The bot also has a licensing system which is connected to a Wix site, with a simple username/password system after they have purchased a certain subscription.
The bot is hosted on Linode.

The help I would need is to:
Fix login bug
Add some features - Relisting items, possibly send mass messages
Slight changes to front end such as moving buttons around

So, the main problem right now is the login bug. Im unable to allow my users to login with their Depop accounts to the bot. One developer has said its a flow error in the code, one has said its a 403 token error, so I am unsure.
Fixing this is the job.

As for budget, perhaps 50£ to fix the login bug? After that, we can talk an hourly rate for other tasks.

If you would like to work with me, it would likely be an ongoing project, so every so often, maybe every couple of weeks I would come to you to add new features or fix bugs etc.

Thanks. Any questions, drop me a message
