I'm looking for someone to give my computer a thorough cleanup and optimization. It’s running slowly, has cluttered disk space, and several programs I never use. I’d like help removing unnecessary files, organizing documents, uninstalling unused apps, clearing caches, and performing basic system maintenance to improve speed. Preference for someone comfortable with Windows 10/11 and macOS, with basic malware scan and startup program management. I’d also appreciate tips on better maintenance to avoid future slowdowns. Flexible on whether the work is done in-person or remotely, but remote assistance should include clear instructions and, if possible, screen sharing.
