Magento Pro

Thailand - Tests: 1 - Portfolio: 6

I am from the US (Miami, FL) and have 16 years of Linux and ecommerce experience. Additionally, I have 4 years of solid Magento experience. I build to high standards, and do not outsource any aspect of your project. I offer excellent post-sales service, including remote backups and server maintenance, as well as technical support and site changes. I have clients using Magento for a variety of of industries in the US, UK, Germany, Australia, Hong Kong, Singapore, Thailand, Italy, and other countries. I typically maintain long-term relationships with my clients to support their systems, provide advice, and make additions or modifications to their sites as required. I favor Amazon EC2 cloud for hosting Magento. With a strong background in systems engineering and administration, I place heavy emphasis on server and application performance, reliability, and security. On average, a straight-forward Magento site takes 1-2 weeks to complete. This time frame allows for server configuration, Magento installation and configuration, and 100% custom design. I guarantee and warranty my work and am available on a daily basis. I am dedicated strictly to Magento development. Though I will install WordPress and even style in the same design as the Magento site, I do not do WordPress projects, and I do not consider myself a WordPress guru. Perhaps one of the greatest assets I can provide your business is great service and advice, based on real experience, and the reassurance that I am available 5 days per week (365 days a year in case of emergencies). Please have a look at my portfolio of Magento sites. I am happy to provide references of owners of active Magento systems (servers and application) whom you are free to contact. I look forward to hearing from you and contributing to the success of your business. Brian Herring
