My Resume: PDF Format | Microsoft Word Format

"I have a passion for 3D Game Development and creating compelling user experiences. I love learning new things and I enjoy finding elegent solutions to complex software engineering problems. There’s never been a challenge I haven’t been able to overcome and I know from experience that there’s nothing I can’t do. I am able to work independently as well as with a team and am able to take direction as required to get the job done."

Physics test application used to aid in the development of the Flight Dynamics Model.

Loopy Software (2011 - 2013)


Expertise: C#, .NET, Flight Dynamics Model, Unity 3D,  XNA Game Studio, 3D Physics, Surface Shaders

Currently developing a new flight simulator. Created a flight dynamics model in C# and .NET. The physics engine calculates the lift and drag components of discrete wing sections and fuselage. The resulting forces and torques are then combined to determine the final velocity vector, position, and rotation of the aircraft.

Also developed a bump to normal map converter as well as a normal map shader. A customized FBX model importer was also created to support bump mapped models in XNA, however, the 3D engine is now Unity 4.1 Pro.

Deadline Solutions, Inc. (March 2011 - Present)

Expertise: C#/.NET, SQL Entity Framework, REST, JSON, MVC 4, Telerik, Mobile Apps, Android, iPhone, MonoTouch, MonoDevelop, PhoneGap, Java, JavaScript, HTML 5, SQL Server Reporting Studio

Extensive C# development. Responsible for the complete development of Watch*IT OPC Express, an OPC tag monitor and alarm system developed. Also developed several mobiles apps, as well as fully validated custom software solutions for Bristol-Myers Squibb and Novelis.


SecureBackup (January 2007 - January 2013)

Expertise: C#, .NET, Windows Forms, Web Services, Multithreading, Encryption, ADO.NET

Developed a highly secure remote data backup solution including client software, database driven web services, and redundant backup servers.
