Whilst living in Italy I have been primary developer on a variety of projects for a US e-commerce site. Projects include high-performance dynamic scaling of images and customisation of clothing and mugs using FastCGI, XML, C++ and ImageMagick.

Survey Engineer, Netcraft

Netcraft is best known for its comprehensive Internet technology tracking surveys, which have been running since 1995. I developed, maintained and ran most of these surveys of up to 50 million Web and SSL sites and processed over 100 gigabytes of data into reports for customers including Microsoft, Sun, BT, C&W, Energis, Rackspace & GCHQ.

Finally, I led development on the high-value Mass Hosting Edition product, aimed at managing large scale shared hosting environments (1,000-1,000,000 web sites).
