    Ecuador - Last active: 3 days ago - Tests: 7

    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!!

    India - Last active: 3 days ago - Tests: 5 - Portfolio: 41

    Hi, My name is Aty. Over the last 7 years since 2007, I have led mufti-functional teams to execute on mission-critical engagements. I did job with large design firms in my starting career for 2-3 years. I then assembled a crack commando unit of the best people I encountered. We take on assignments, right-size the solution to the problem, and then use the team approach: an architect to ensure you have a platform suitable to your needs, razor sharp analysts to document the deliverable, creative designers for graphics, and masters of code. We then put very cheap SEO and maintenance folks to ensure your rankings remain at the top, and your site runs blazing fast. Each of these people bill at different rates, so you get maximum bang for your buck. When you hire anyone at Quinji, you hire the team resources. You will not suffer if someone is not available. We have the breadth of skills and depth of resources to ensure your project is on time and on budget. I am native US English speaker and this feedback is given to me by more than 20 different clients which they found a plus point while making conversation when they are outsourcing their work for better communication and understanding. Always available on Skype for voice or text during my working hours. I completed 2600+ hours on odesk with 4.96 star feedback out of 5 up to June 2014. Hope it will boost some confidence inside my capabilities to complete your assignments successfully. Looking forward to hear from you. ********************************************* My Technical Skills are as below: ------------------------------------------------ Security Expert -> SQLi/XSS, Trojan Removal, Malware and Malicious Code Removal, Security Configuring on servers, CSF, mod_security, DDos Attack, Phishing attack, Iframe, eval and base64 signature detection, VPS and Dedicated server Management, Monitoring, cloaking, pharma hacks, shell detection, spam blocking.
