I need help cleaning my computer and organizing files

I’m looking for a tech-savvy helper to clean up my computer, remove unnecessary files, and organize folders for easy access. The goal is to improve performance, free up disk space, and set up a simple, logical filing system. I have both Windows and some Mac files, so please be comfortable working across platforms. The work includes running a basic cleanup, removing duplicates, updating software where appropriate, and giving me tips to maintain order. If you can also back up important documents before making changes, that would be amazing. I’d prefer a patient, detail-oriented approach and a quick hands-on session in the home.
