    I've got great php/mysql/css/html,javascript skills and use linux, ssh, git, svn, mercurial, apache, nginx and varnish on a daily basis, and I'm fluent both speaking and writing English and Spanish, I know a bunch of other languages to a lesser extent. Some of my work includes Magento(Community and Enterprise), Wordpress, Blender, Linux shell scripts, windows USB drivers, Server administration, configuration and much more. Most contracts require me to use Magento where I have done the following tasks: Event Observers. SOAP Api Extensions. Complete Custom Modules. Core Overrides. Upgrading Magento to Specific or Latest Version. Theme Customization. Custom Code Debugging. Everything else really. I've done everything with Magento at this point. I'm also comfortable using c, c++, python, and possibly any other normal programing language, either for web development(django) or gtk, qt and desktop applications. I prefer to use free software or open source tools, and while we can talk through Skype, I'll probably will ask you to use something like Jitsi or some other tool, to talk to me, you can also call me to my US number anytime. I'm familiar with SIP and VOIP frameworks for IM and voice applications, I can help you setup an Asterix server or a phone system for your company. I have extensive database experience and I've used mysql, postgres and sqlite to create very complex db schemes. Give me a try there is a high probability of you being happy with my performance. Cheers!!  less
