Phrases for "aptitude for technological devices" to include on CV?

Hi everyone,
I am wondering how to describe this:

I am good at using computers, smartphones and other technological devices, I know much about and make use of many functions on those devices that the majority of people don't know about. I am good at searching things on the Internet and finding out useful features. Besides, I have learnt some courses on using Word and Excel so I can use them well.

I want to show this on my CV's Skills/attributes part but couldn't find appropriate phrases, is "aptitude for technology" ok?
Is there other words describing this?

Thank you a lot!
