Oct 1999 - Jul 2013
Looked after the corporate internet provisioning and usage billing and reporting systems. This was based on Cisco Netflow, SNMP and a bit of RADIUS on a Python and C code base. There were also user web interfaces into this. The processing of all the customer IP connections produced large volumes of data that was always a challenge to process and store. Made various changes and performance improvements over the years, including adding distributed processing into the mix, porting from Sparc to i386, and multi-threading. Recent projects have been Java web services oriented and an excursion into android programming.

May 1996 - Oct 1999
Consulting all sorts. This was a varied role which included Customer pre-sales, site installations of UNIX systems, NT systems, Routers, Firewalls, VPN's, Software and Security audits. There was some software development, including an e-commerce web site of questionable repute. There was also an ISP in the form of Planet Internet for which I administered the systems, routers, web hostings, DNS, email and developed software and provided support as needed.
