I’m looking for a tech-savvy person to give my computer a thorough clean and optimization. It’s running slowly, with clogged temp files, outdated software, and a few stubborn startup programs. I’d like someone who can safely remove junk, organize files, update essential software, and set up a lightweight maintenance routine. If possible, please bring any necessary tools to back up data and perform the cleanup without risking my existing files. I prefer a calm, methodical approach and clear explanations of any changes made. Location is Dublin, Ireland, and remote work isn’t suitable for this request—on-site visit requested.
