About Christopher Chang
I help companies build 0 to 1 personalized consumer fitness experiences to improve healthspan across digital software, connected hardware, and in-person facilities.• 2x Founder and Product Manager with 9 years of entrepreneurial experience in the fitness industry.• Deep domain expertise in fitness coaching & education, in the top 0.5% of trainers at Equinox.• Developed technical depth as a Hardware Engineer for 4.5 years before transitioning into software.• When I'm not working, you can find me enjoying outdoor activities, playing video games, indulging in fantasy novels, or sipping on a craft beer.My Story:I love to play outside like a large child, from rock climbing, handstands, to pick-up football. The activities I enjoy require a certain amount of physical ability and I’ve had times in my life where my ability to do those things have been taken away. Living without those things was a big step down in quality of life. Since then it has been my mission to remove these barriers for myself and others so we can all pursue what we love without restriction or hesitation. I left my career in engineering to pursue my passion for helping others improve their healthspan.
Listed skills include Engineering, Mechanical Engineering, Matlab, Finite Element Analysis, and 31 others.
