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. I use technologies such as Javascript, Jquery, Bootstrap and Laravel to make user friendly websites that adapt to any screen size. I listen to a lot of music and play cello in an electro-acoustic band called Sonori - and create experimental cello based music as 'The Mystery Guest' -
