- Increased the efficiency of RenderView, a Windows physics-based ray tracer written in Visual C++, by at least 10 times after researching, implementing, and testing a spatial partitioning algorithm.
- Converted a legacy physics-based global illumination renderer that was written for a SGI with IRIS GL and Fortran 77 to Linux with OpenGL and C. Exceeded previous polygon limitations and was approximately 6 times faster when using hardware acceleration.
- Improved PRIMUS, a Visual C++ Windows OpenGL 3D model viewer and conversion tool that aided in-house integration of two physics-based thermal signature prediction programs. One improvement made it nine times faster to import MUSES thermal signature files through a more efficient algorithm that used caching and a dynamic lookup.

Experience
- CloudI: A Cloud at the Lowest Level (Development)https://cloudi.org
CloudI is an open-source private cloud computing framework for efficient, scalable, and stable soft-real-time event processing.
- Modernizing Legacy Software: MUD Programming Using Erlang and CloudI (Publication)The need to adapt legacy code and systems to meet modern day performance and processing demands is widespread. This post provides a case study of the use of Erlang and CloudI to adapt legacy code, consisting of a decades-old collection of multi-user game software written in C, to the 21st century.
- CloudI: Bringing Erlang's Fault-Tolerance to Polyglot Development (Publication)Clouds must be efficient to provide useful fault-tolerance and scalability, but they also must be easy to use. CloudI (pronounced "cloud-e" /klaʊdi/) is an open source cloud computing platform that is most closely related to the Platform as a Service (PaaS) clouds. CloudI differs in a few key ways, most importantly: software developers are not forced to use specific frameworks, slow hardware virtualization, or a particular operating system. By allowing cloud deployment to occur without virtualization, CloudI leaves development process and runtime performance unimpeded, while quality of service can be controlled with clear accountability.
