    Dmitrii Korotovskii

    Senior Software Engineer

    Russia - Tests: 3 - Portfolio: 2

    I have over 6 year's experience in PHP/Web development. I use PHPStorm as my primary IDE. Source-code is always stored in Git. Git is my favorite distributed revision control system. I also prefer do rebase on my branches and cherry-pick in emergency situations. For debugging PHP applications I use Xdebug and strace in very complicated cases. I'm an advanced Linux user, I usually write small bash scripts to make my life easier. I can setup working environment from scratch on server, but it's better to do it via provisioning system like Ansible.
