Good day,
I will gladly help you with your project. Previously I developed a LinkedIn search tool for a recruitment agency. The tool searched for people given a certain search filter. The matching people were then added to a spreadsheet, if not already in it. This helped the agency to better keep track on people they have contacted or not, and see any new people that match the given search filter. Your project is similar, so I already have a good start. Is there any language you prefer for this application (Python, C#, etc.)?
If you have any questions, do not hesitate to contact me.
Greetings
Matthias
