I'm currently Head of Development at Guide Education, where I built a video-based VLE (virtual learning environment) from the ground up, as well as various other platforms and tools. I elaborate on all this over on Linked In.
I've worked in Moscow, Nizhny Novgorod (also Russia), London and elsewhere. I was Senior Developer at Espresso Education (later bought by Discovery Education) and later Guide Education, so I know a fair bit about e-learning systems and associated UIs.
I'm comfortable with all versions of PHP, up to and including the current PHP 7, as well as MySQL and MariaDB. I also use no-SQL databases occasionally like MongoDB. I routinely work with a plethora of PHP libraries such as GD, cURL, DOMDocument and others. I'm also au fait with MVC frameworks like Code Igniter.
I'm a REGEX sadist (various flavours) and love working with XML technologies such as XSLT, XQuery and XPath.
