Need computer cleanup and optimization help

Hi there, I’m looking for a friendly tech-savvy person to clean up my laptop and optimize its performance. It’s been running slowly, has a few unnecessary programs, and there are some old files taking up space. I’d like someone to run a thorough disk cleanup, remove bloatware, organize files, and set up basic maintenance routines (automatic updates, antivirus scan, and monthly cleanup tips). Please also advise on privacy-safe ways to manage data. Comfort with Windows and macOS is a plus. Flexible on timing, but I’d prefer the work done in one session if possible.
