    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.
