About Christopher J. Keller

Your IT Guy — From Mainframes to iPhones

With over 41 years of hands-on experience in technology, I’ve seen it all — from punch cards and mainframes to the pocket-sized power of today’s iPhones. I’ve supported clients through every generation of tech, adapting, evolving, and always staying a step ahead so they don’t have to.

I work with businesses of all sizes, from solo entrepreneurs to established companies. My background spans industries as diverse as retail, wholesale, clothing manufacturing, and even 3D animation and rendering for motion pictures. Whether it’s syncing your email across multiple devices, building a custom FileMaker database, securing your network, or integrating smart home devices — I’ve got you covered.

How I Work

Technology can be frustrating. My job is to take the stress out of it.

I offer straightforward, honest support — no upselling, no jargon, and no unnecessary complications. Just clear answers, practical solutions, and peace of mind. And if I don’t have the answer? I probably know someone who does.

A Bit More About Me

When I’m not solving tech headaches, I’m usually out cycling the streets and foothills of Pasadena, especially around the Rose Bowl. It’s my way of recharging — just like I do for your devices.
