Aspiring IT Support Technician | Electrical Engineer | CompTIA A+ (in progress) | HDip in Computing @ NCI | Dublin

I'm moving into IT support after more than 10 years of hands-on technical troubleshooting in Brazil, first as a freelance electrician and then running my own electrical installation, maintenance and CCTV business.

Today I'm studying for a Higher Diploma in Computing at the National College of Ireland and working towards CompTIA A+, with a long-term goal of growing into cybersecurity.

This profile documents what I'm learning and building along the way.
