I'm a student and programmer living in Scotland, currently studying Language & Linguistics at the University of Aberdeen. I'm best known for contributing to the PHP programming language, among various other things. You can reach me via email at firstname.lastname@example.org, or on Twitter at @notajf.
My blog can be found at blog.ajf.me. In October 2015 I gave a talk about PHP 7's Scalar Type Hints at PHP North West.
