Hey! I believe that I'm the perfect fit for this job, as I have a lot of experience with automating similar tasks Some of the platforms may not have a direct API, so the bext way to extract the data might be by simply automating the mouse clicks themselves, but this is something we need to define for each specific platform I'm excited to work with you, send me a message and let's discuss the details
