What project management system to use for self-control?

Question

Project management

Salute, gentlemen and ladies!
I am an engineer who occasionally works on multiple projects at the same time, and it can be very difficult for me to switch from one project to another. Especially when one is dedicated to communication, and the second to monitoring. And I would like to know from you what project management system can be used for self-control? All systems with which I faced are calculated on managers. And I would like for myself, with the ability to add files, leave notes / entries, and, if possible, with cartography.
Thank you for your help.
