Software Engineer

• Performed code reviews and design reviews for portions of XFDTD being developed by other software engineers.
• Assisted with implementation of an OpenGL ray tracing tool to provide a generic method for generating a mesh of all objects.
• Modified the existing implementation of XFDTD calculation engine threading routines to increase scalability.
• Learned MPICH (Message Passing Interface toolkit) then designed and implemented the core functionality of the distributed computing based method of calculation in the XFDTD calculation engine.
• Distribute the space at startup.
• Allow key pieces of data to transfer across machines at the right time to allow the time stepping to continue properly
• Concatenate the data when ready to write out results to disk.
• Designed and implemented a faster version of the SAR averaging routines that would function on one CPU, across multiple CPUs in one machine, and distributed across multiple machines.
• Gathered requirements for an FDTD based thermal solver by communicating with customers and colleagues to identify how the tool would be used.
• Researched numerical fundamentals for, designed, and implemented a thermal solver in the XFDTD calculation engine which would incorporate the thermal effects of EM absorption on objects.
• Searched research papers to discover a method for calculating a time step to make the simulation stable.
• Design requirements included performing the computation with threading and distributing processing.

Junior Software Engineer

• Designed and implemented Feature subsystem structure for Wireless Insite. This included making Interface type classes and allowing those to be broken into more specific classes to represent cities, buildings, sub-buildings, walls, terrains, foliage, and various other electrically significant aspects of outdoor scenes.
• Designed and implemented building simplification routines in Wireless Insite to reduce the computational complexity of features to allow the calculation engine to run faster.
