Dear sir,
My name is Volodymyr and I am an experienced developer who can help create and maintain a Jarvee style Twitter tool.
I have the experience and expertise to develop the tool with the key features that you have mentioned in your job post i.e. managing a great number of accounts simultaneously, running via proxy to avoid ban, automated follow/unfollow functionality, targeted following through integromat or other software, automated retweeting, humanising use to avoid bans- liking etc., and tracking account status (Followers, Following, Daily activity, Active/Banned etc.).
I can estimate that it will take approximately 80-100 hours to complete the task. I am confident that I will be able to deliver the project within this timeline and create a robust system for you.
I look forward to hearing from you and discuss how I can help you with this project.
Thank you for your time and consideration.
Sincerely,
Volodymyr
