Mainly doing PHP development. Transitioned from CodeIgniter to Laravel. Yeah, that sounds so mainstream.
Composer changed our world for the best. Had to mention it.
No more .NET or Java. My head hurts a bit less now.
Also, MediaWiki power user.
Rudimentary Photoshop knowledge (able to install it).
Last but not least, cannot stand WordPress (or to be precise, its overuse).
