    Just arrived here and looking for some clients

    Australia - Last active: 11/06/2013

    There are not many parts of Linux and the applications that run on it that I have not worked with, both as new implementations and repairing horribly broken systems . From the web side I have recently been working with nginx, postgresql and ntfs4 but have also am fluent in Apache, mysql and php. I have looked after Windows and Mac systems and integrated them all in networks where all devices can see and communicate securely and transparently In the last few years I have moved many of my clients from qmail and postffix to Google Apps. I have a strong understanding of DNS and managing of domain names. For a few years I worked in VoIP building enterprise systems using asterisk. If you have a problem or you want something done I am happy to work out with you if I am suitable.
