Chatbot as chrome extension in java

Hello, I'm looking for a programmer who creates a chatbot which works with [login to view URL] bot should go to certain profiles and then send a message. It would be important that the chat bot is similar to a human. So it should be set different random pause intervals. There should also be a database into which the chatbot then stores the name of the profile, the message, the time and date where it sent it and the link to the profile. With this database should also be communicated that, for example, after a week, the user is again written with a different text. The chatbot should be activated when I am in my account. Also conceivable would be a Chrome Extention or something similar If you can make such a Chatbot for me, I am pleased about a contact of you.
