Need IT assistance for system optimization and troubleshooting

I'm looking for a freelance IT expert in Ireland to help optimize my home workstation and troubleshoot a few issues. The tasks include software updates, installing a reliable backup solution, setting up automatic security scans, and diagnosing intermittent network connectivity problems. Preference is for someone who can explain steps clearly and avoid unnecessary jargon. I’d also appreciate a quick assessment of my current hardware to recommend potential upgrades. Access to remote support is okay, but some on-site visit might be needed for hardware checks.
