I've been dropshipping for not so long and recently got interested in the following question: is it possible to automate all the complex processes in this job? Who can advise?

Depends on what you mean by complex processes, for example, if you need to automate the execution of orders, attracting suppliers, checking the goods and all that kind of thing, you can easily simplify this task by using special software designed for dropshipping, some variants of which, by the way, are presented here https://gologin.com/blog/best-dropshipping-tools.
