Lead Software Engineer
2013 - PRESENTTec-Masters, Inc.- Deployed a new development process that focused on test-driven development (TDD) and automated unit testing, significantly increasing test coverage, and reducing regression rates.
- Updated the configuration management process to use better-integrated tools, such as Jira and Bitbucket, and increase automation of software packaging and deployment.
- Led a team to design and implement a real-time application to merge simulated radar data with live radar data to facilitate conducting exercises and training in the field with US Army soldiers.
- Led a team to design and implement a real-time application to record high-speed radar data for verification and analysis.
- Led a major development effort to re-architect our radar signal injection application to better utilize the memory architecture and instruction sets of modern x86-64 server hardware, leading to a 10-15x improvement in application throughput.
- Reverse engineered the signal injection algorithms and wrote white papers to document the algorithm designs, references, and assumptions for future developers.
- Conducted peer reviews on code submissions and provided critical feedback to mentor and train younger developers.

2006 - 2013Tec-Masters, Inc.- Developed an application to inject simulated target scenes into the Terminal High Altitude Area Defense (THAAD) radar system.
- Ported the signal injection software from a legacy SGI MIPS architecture running the IRIX operating system to a modern x86-64 architecture running Red Hat Linux.
- Automated the analysis for software requirements verification using Linux scripting languages, reducing the verification timeline from over three months down to two weeks.
- Replaced a legacy, paper-based configuration management process with a new process using modern tools, notably Git and Bugzilla.

Employment
Experience
- Simulation-over-Live Driver (SOLD) (Development)
A real-time application that injects simulated radar targets into the Terminal High Altitude Area Defense (THAAD) radar system. I was one of the software engineers responsible for implementing the real-time variant of the SOLD algorithms for use in hardware-in-the-loop testing of the radar. I was the lead software engineer responsible for the later redesign of the SOLD software to increase real-time stability and performance on newer server hardware.
- I&Q Merge Unit (Development)
A real-time application that combines simulated radar in-phase and quadrature (I&Q) data with live radar data, such that radar equipment in the field can observe simulated targets. This allows US Army soldiers to conduct exercises and training in the field with their own equipment. I was the lead software engineer responsible for the design and implementation of this application.
- I&Q Recorder (Development)
A real-time application that records several sets of radar in-phase and quadrature (I&Q) high speed data, along with timing information. This data recorded by this application was used to verify the accuracy and real-time performance of other I&Q processing systems. I was the lead software engineer responsible for the design and implementation of this application.
- I&Q Generator (Development)
A real-time application that produces randomly-generated radar in-phase and quadrature (I&Q) data to facilitate fuzzing and performance testing of other I&Q projects. This application was required to maintain the highest possible data rates for weeks on end to stress the downstream applications. I was the sole developer on this project and completed its development within three months.
