* Designed and developed a sophisticated calculation engine in C++ for manipulating multi-dimensional arrays as part of a team effort. - Designed and developed a custom function and procedure mechanism. This allows C++ developers to add functionality almost trivially to the calculation engine and to do this dynamically through shared libraries. - Implemented various spreading and aggregration algorithms that manipulated data across mappings, particularly with respect to time series data. * Designed and developed a flexible database caching mechanism in C++ to minimize disk access. This brought a 20-fold increase in speed to key areas of the system. * Ported multi-dimensional database system to Linux (written in C). * Designed and lead development of a content management system written in Java. This subsystem was a crucial component of the redesigned enterprise product as our company shif
