In a nutshell: I do logos, websites, and apps.
I have a long history with Wordpress which I use to build the majority of my websites; I also use several pieces from Symfony to keep websites and web apps well tooled. I've spent a crazy amount of time with Xcode writing iOS apps and at this point, I think we're more than friends.
For design and mockups, I use Sketch, quite literally the best vector design tool ever. If you're a designer and haven't heard of it, stop what you're doing and visit that link now.
