In my free-time I like to tinker with a bunch of languages and try out different things.
When I'm not tinkering around, or working on open-source projects, I'm usually working.
I lead a medium-sized team of Full Stack developers, working on a variety of things, from websites through to mobile apps, games, backend tools, and kiosk touchscreens/apps.
Here is my preferred stack when working:
PHP - using Laravel to do the heavy-lifting backend work and building RESTful APIs
CSS - for 2D and 3D animations
Bash - for scripting and general purpose tooling
HomeBrew - for package management
MacOS - It's unix and is the best environment I've found for my stack
