Katrina O’Reilly

Katrina O’Reilly is a technology writer from Jaynesfield, Wisconsin, with more than a decade in the industry. Today she leads our PC optimization coverage of cleaners, tune-up suites, and disk utilities, and she tests every one of them in real before-and-after cleanup scenarios on her own machines.

She built her reputation in phone data recovery, spending years on hands-on reviews of iOS and Android recovery tools, and that byline still stands on many of our recovery guides. Along the way she earned CompTIA Security+ and CISSP certifications, plus Google’s Associate Android Developer and Apple’s iOS App Development with Swift.

As a mother, Katrina cares about the balance between freedom and protection for kids online. She advocates for online safety and digital literacy beyond her writing, speaking at conferences and working with schools and parent groups.

Off the clock, she is usually on a Wisconsin trail: hiking, family bike rides, and the occasional geocaching adventure with her daughter and their dog, Max.
