    Over the last 8-10 years, I've developed e-commerce websites, helped business owners increase and improve their website conversion rates, and have developed a PHP application that is specifically designed to help with website conversion rate improvement (SuperPageSplitter.com). I am a website conversion expert, website business consultant, email deliverability consultant and above all else, an experienced server administrator. This typically entails me providing advice (and often helping with the implementation of ideas I suggest) to develop a client's website, improve it (i.e. specify a "call-to-action" more clearly, track visitor data, and so forth), develop customer relationships (using e-mail marketing as a tool) and to make sure it has the framework in place to support the client's business -- whether that business is offline or online. My main focus is automating tasks, and this is what I specialize in helping my clients do in order to improve their productivity, help increase their base efforts exponentially, and free them (or their employees) up to work on more important things where the business may be concerned. As a programmer (PHP/Perl/Python/Shell Scripting), internet marketer, conversion rate expert, and e-mail deliverability specialist it is a typical day for me to help put together an e-mail campaign for a client's customers, track the data the customer's provide (via feedback forms, or activities they perform on the site), create shell scripts or PHP scripts to automate tasks, and ensure that the server it's all running on is secure. As an experienced server admin with 10+ years experience, I help clients with Apache, NginX, PHP, MySQL, BIND / named, and PCI Compliance. In fact, an article I wrote on PCI Compliance was published by CardPaymentOptions.com, which is a credit card processing online guide for new merchants: http://www.cardpaymentoptions.com/credit-card-processing/pci-compliance-guide-for-e-commerce-merchants/ In addition, I am very familiar with email marketing setup, email marketing software (such as Interspire Email Marketer, MailChimp, aWeber, ConstantContact, etc), and am very experienced in setting up the mailing environment properly and in such a way that email can be delivered to the inbox rather than the spam folder of the intended recipients.  less
