Greetings,
I think here you are looking for someone to develop for you a python script that will scrap users details from telegram public groups with filtering "last seen recently" only.
I understood your project description. I have worked with telegram api before.
I am an expert in PHP, JavaScript, Python, Web Scraping, Software Architecture and I am really interested in your project.
I am really confident that, I can do this with 100% accuracy and ready to start now!
But I want to know more about your project. So, can we discuss more?
Thank you.
