    I have been working in the internet industry as a full time professional web designer since September 2006, accumulating a wealth of knowledge and experience during these past 8 years. I specialize in best practice front end development; this covers web design including content management system integration (such as Joomla and Wordpress), website accessibility, usability and on-page SEO. The advent of smart phones and tablets have changed the web landscape forever, your customers are no longer tied to a desktop or laptop; instead they will be using a myriad of devices to view your website, as such I am an advocate of responsive website design (RWD). RWD means that your website will be device agnostic, functioning perfectly no matter the device your customer is using to view it, e.g. iPhone, iPad, Android phone or Android tablet.  I have extensive experience managing large scale internet projects and can assist with consultancy, technical document creation, wire frame creation, supplier identification and management and project management.  ❀Why Me???: - ❀❀❀Already completed 150+ project with impressive feedback and rating.❀❀❀ - Can work with USA, Canadian and Australian local official time. - Available on gtalk, skype, email and phone. - My average response time for replying email is only 3 min. - I have already worked with several USA, Canadian, Australian and European company. - Well-organized and efficient. - Strong background in all phases of network and support. - Self-motivated and assertive. - Quickly learn procedures and methods. - Enjoy working with people. - Efficient and courteous. - Able to work with others toward a team goal.
