The Mystery Guest Web Design is based in Katoomba, NSW Australia. I have been designing and building websites since 2000, and building smartphone apps since 2011. I specialise in database driven sites using PHP and mySQL and use technologies such as Javascript, Jquery, Bootstrap and Laravel to make user friendly websites that adapt to any screen size.
