EXPERIENCE

Application Software Engineer,

Clear Capital, June 2012 to Present

With ColdFusion and SQL, extended property valuation gateway to inter-operate with Freddie Mac product line.

Sr Software Engineer,

Dibbs International, April 2011 to February 2012

tags. In Ruby on Rails and MySQL, designed an implemented system for acquiring and merging real-time data.

Built high speed tag retrieval system using redis.

Software Engineer IV, Game Development,

IGT, April 2009 to October 2010

In C++ and Lua, designed and built wager type video games. Designed and implemented a library for selecting

the angle of view of a multifaceted object as it spun. Input was max velocity, starting face, ending face, and spin

duration. The angle of view was calculated as a function of time using a Riemann Approximation. From the

angle, a frame was selected from a pre-rendered movie made by rendering every nth fraction of a degree, allowing us to spin

hi-end rendered objects in real-time.

System Architect,

Purring Lizard, January 2009 to April 2009

In C++, designed and implemented 3D engine, in DirectX. Built custom shaders in HLSL.

Lead Graphics Programmer,

Metron Media, Inc., October 2001 to December 2008

Built fast, frame limited, render engine in C# using DirectX. Implemented a smooth quaternion based system

for positioning camera. Optimized the render pipeline to achieve frame rates at or near refresh rate on

hand held devices. Designed and implemented test-bed framework that significantly reduced development costs.

Contributed several original designs to Asbuilt's store of intellectual property

(including patent #7130774),

helping to secure a solid competitive advantage. Optimized for speed and expanded capabilities of 3D engine

for rendering floor plans and elevations. Added a quaternion based camera for super smooth transitions.
