These included the control and infrastructure for an animated 3-D model for the inauguration of Shell's Pearl GTL plant in Qatar, and an automated multi-media capture, management and upload system for Ford's stand at the NAIAS in Detroit. All software was written in Python and used TCP & UDP networking, Twisted, event driven asynchronous programming techniques, DSLR/Video remote control & capture hardware interfacing, BrightSign scripting, libgphoto2, gstreamer and Django. The projects ran on Ubuntu Linux and Mac OS X. Software development was supported by git, Jenkins & Jira. My work resulted in the successful deployment & execution of innovative, stable and high quality award winning exhibits.

July 2010-July 2011, JPMorgan Chase, London. While at JPMorgan Chase I worked on two separate Python development projects:
The first was a proof of concept system evaluating the replacement of the current Java/Sybase equities & derivatives trade booking system. Technologies used included Python, Jython, Java, Objectivity object database, Sybase, Twisted, metaclass programing, HTTP & TCP/IP networking. I designed and developed various parts of the infrastructure to enable the data model, high-throughput transaction processing and interoperation with existing systems. Notable was the development of a bespoke ORM, using metaclass techniques to implement a declarative pattern. The projects were written mainly in Python/Jython and ran on Windows and Redhat Linux.
The second project was for the FX business, to replace an existing mainframe risk management system using the bank's Python based Athena platform. I developed up-stream feeds for STP of trades to the backend. This used Python, IBM Websphere MQ, XML and xpath. I co-ordinated with several teams in different timezones to successfully put the feeds into production.
