I'm looking for a knowledgeable tech to clean up my desktop and laptop, remove junk files, and optimize performance. The goal is to improve startup speed, organize files, and update software safely. Please assess both Windows and macOS devices, run a malware scan, uninstall unused programs, and set up basic backups. I prefer guidance on routine maintenance and achievable upgrades within a reasonable budget. If you offer remote tips or on-site help, include your availability and any tools you use. Located in Ireland, English communication is preferred.
