DionCoffeeMaker
===============

Our poor coffee maker :(

We make it to brew some coffee in the office. 

It was originally developed by a ASP sympathizer PHP developer. So, it works but god knows whats wrong with it!

So we are looking PHP developer to fix our coffee maker script and also join our team.

On every sip of coffee we drink, we are wishing for a better coffee maker. 

Fork it, send your comments and if you are in Istanbul and looking for a job as PHP developer, contact us.
