    I have gained great knowledge of W3C standards and good practices implementing them on many websites during last 7 years. My objective is helping new companies build nice websites which are both easy to administrate and fast in speed (PHP optimizations). I also have a good knowledge of OOP: C++ and C# are languages I use to build desktop applications.I use Zend Framework for creating complex PHP applications that scale well, follow the best practices (MVC and other programming patterns) and SEO optimized. Another field of my work is proper setup of web hosting servers. I am very proficient with RedHat based operating systems (CentOS, Fedora, etc.) and experienced in tuning web servers for performance and installing required components remotely: the LAMP stack (latest Apache, MySQL, PHP) and compiling software that is unavailable as rpm packages.  less
