Hello,
I can do your project using Python 2.7 with selenium, beautifulsoup.
This is the scraping flow:
1 get first name, last name, birthdate from csv1
2 login linkedind
3 enter the detalils from first person to search bar
4 get all the results
5 for each person in results above check the birthdate
5.1 if the birthdate is identical save the person details to csv (should I continue scraping to see if there are other person with same birthdate???)
5.2 if don't find person by birthdate, save the results in posible matches
repeat steps from 3 to 5.2 until i search alll persons
If you tell me how many person i'll have to search, i can estimate how long it will take.
Contact me on PM if you have any questions
Regards,
Daniel
