Hello there!
I have built several member adding and messaging bots for telegram.( you can check my reviews for the corresponding projects )
My bot will join a group automatically and then collect all the usernames.
I will use the official telegram API to do this.
Only limitation to this is we can send only 30 messages/second.
My skills & experience:
-- 2.8 years of experience in building automation tools using python.
-- Worked for Infosys ( a multinational company ) as Automation engineer.
-- Worked on ATP world tour 2017 project as Data analyst.
-- Built more than 56 web scraping projects till date ( 24 on freelancer.com, please check reviews )
-- Websites i have built scraping tools for include Telegram, Linkedin, Facebook, Gmail, Tinder, Okcupid,
Outlook and many more.
-- Can bypass websites protected with captchas ( reCaptcha v2 and invisible Captcha ).
Looking forward to hear from you.
Thank you, have a nice day!
