About Me
Hands-on tech.
Real solutions.
I'm a hands-on tech specialist with strong experience in hardware, troubleshooting, and system setup — over 20 years of working with computers, from early hobbyist builds to full infrastructure projects.
I build systems, diagnose issues, and improve reliability. Whether it's a failing component, a network that won't cooperate, or a service that needs deploying — I find the fix.
I'm focused on IT support and systems administration roles where I can bring practical, hands-on value from day one.
