I am looking for an webdeveloper, who is experienced in PHP and MySQL and the development of a performant (!) specialised CMS. My Website is actually working with Wordpress but because of the huge data-volume (more than 10.000 posts and over 10.000 views each day) the performance is not so good, i got a few MySQL slow queries and also the PHP Code (which i wrote by myself) is not so good. I am planning a new design and in the same time i want a better performant code. Maybe you got your own CMS and that would fit to my website in some ways? Maybe you are interested in creating a new one for me? Or maybe there is some CMS you know, which could be used? Because the website is really special it will take some time to work on it, but I am going to do write the functional specification in detail, I think that will take 20 to 40 pages, so you can work on your own. One thing which is really important to me: The CMS should be really performant and it should take not longer than 2 or 3 seconds to list a few movies in a list, better would be just 1 second or lower. Maybe it would be good to have 2 server, one to work with the whole PHP code and creating new content and so on, and one server where just HTML files will be saved when we got changes on the site, so the user just have to load HTML, CSS and images. Okay, I think the most important things are said, when you got questions feel free to contact me. :)
