    With over 10 years of expertise in web development and being connected to the WWW from 1997, I always wanted to create or help to create websites. My goal is to work on large projects and ensure adequate quality and high scale of web development. My areas of expertise are E-commerce, E-learning, job portals, large news portals, corporate websites with specialized features, media galleries, forums and other web content solutions. I have also extensive skills in Linux hosting servers administration (L.A.M.P. + DirectAdmin/ ISPConfig/ CPanel). Years of work have resulted in creation of a full-featured CMS and E-commerce software that serve as basis for my Customers' websites. I chose PHP/ mySQL/ DHTML as primary technologies for web development since the beginning and I continue to improve my expertise now, because Internet is a quick fox, I need to go faster to challenge other players and to catch the game before.
