I use Windows and Mac systems daily for graphic design, web design, photography, and videography.
I have experience with hardware and software troubleshooting, system upgrades, small networks, and data backup and recovery.
I've pulled data, telephone, and AV cable through walls in homes and offices, connected and set up complex home theater systems, and installed closed circuit security cameras.
I am the official "tech consultant" to all of my friends and family...and if you're reading StackExchange, you probably are too. I feel ya.
