    James Mashore

    Professional System Administrator/Developer - PHP/MySQL/JQuery/HTML

    United States - Tests: 7 - Portfolio: 3

    My experience spans over 30 years of software and system administration duties. I have developed systems ranging from full featured commodities trading platforms to EPA Compliance and government regulatory Electronic Reporting Systems. I have spent the last 10 years developing systems using PHP/MySQL/JQuery/Java Script and HTML. My administrative skills include MySQL, several flavors of UNIX, CPANEL/WHM and Apache. I've installed and setup a variety of mail servers also. I'm an old school developer. I don't believe in using complicated frameworks or non-standard programming methods that simply drive up the costs of maintaining/extending any code I develop. In addition, I am knowledgeable in the Open Cart environment and have developed several add-on extensions for it. Recently I developed several REST applications using the SLIM framework. I have considerable expertise in setting up cloud environments. This includes public cloud servers as well as dedicated hardware systems. It doesn't matter if you need 10 lines of code or 10,000. If your in need of someone that can write code that is dependable, cleanly written and extensible then I am your perfect choice. As a side note - I'm well over 40, and in the US. That means if you send me a message at 1:00AM in the morning I probably am not going to see it until later that day. I reserve my all night work sessions for paying customers.
