I have strong experience in PHP and web development which includes JavaScript, CSS, HTML and using libraries such as jQuery and etc.
My work environment is Linux, so that I am able to administrate server which runs Ubuntu/Debian or CentOS distribution.
I've done a lot of API integration into various systems - starting off payment gateway such as Paypal, Bitcoin, Skrill Money, Yandex Money and ending off RIPE NCC, WHMCS and etc.
