Mac KensingtonGamer. Collector. Salesman. Maker.
Always building the next thing.
Some people pick a lane. I bring the whole garage. From buying, selling, and trading to fixing phones, creating brands, and connecting people with opportunities, I turn curiosity into something useful.
JMac Design is the home base for that energy. Mac Kensington and Cardboard Crack are my independent brands. Professional sales and partnership work has its own place here, too.
“For every typo I make in life, I have another skill added to my arsenal. Hey, look at that. I leveled up.”
