- Designed, developed, tested and maintained applications using C++ programming language.
- Designed code using UML.
- Maintained code in 'git' repositories in Perforce.
- Designed software for CentOS real-time operating system.
- Implementation of code was in layers 2, 3, and 4 of the protocol stack.
- Allowed exposure to TypeScript, JavaScript, and HTML.
- Performed unit testing (gtest) on application components prior to release.
- Participated in agile development (SAFe) of products within cross-functional frameworks.
- Reviewed and modified unit and integration tests to improve software quality and reliability.
- Met with stakeholders, product teams and customers throughout system development lifecycle.
- Field tested applications

Senior Software Engineer
Information Technology Engineering Corporation (ITEC)
Aurora, CO
07.2008 - 03.2010
- Contracted to Northrop Grumman via Raytheon.
- Worked with an independent research group to assist in the incorporation of an API that allowed more precise emitter identification.
- Modified code to allow for future asset addition.
- Code points for implementation were in the Correlation and Reporting Subsystem
- These code sections (written in C++) were modified using the department’s coding standards
- Testing was then performed over a series of months (during which time, the API went through multiple revisions)
- The focus on testing contained two main parameters: accuracy and performance
- Accuracy was tested based on comparison with theoretical models (from the research group)
- For performance testing, new code functionality was developed to trace the timeliness through the code modified for this application.
- Reassigned to O&M group to assist with clearing backlog of problem reports and to research, design and implement an agile process within the highly unpredictable O&M enviroment

- Developed a data collection system for the next-generation radar system.
- Contributed to networking code for a new radar system using TCP/IP.
- Integrated object-oriented design and development techniques into projects to support usability goals.
- Developed algorithms to orchestrate repackaging radar data into a form available for post-processing
- Design followed strict object-oriented development philosophy using an OOAD tool (Embarcadero's Describe)
- The implementation was an application written in C++ and targeted for a Sun Solaris (UNIX-based) server
- Developed prototypes for a waveform generator
- Introduced the use of design patterns to speed up the development process and acted as a focal point for questions regarding patterns
- Was then added to the team as a contributor for changes to the radar control unit for a new radar system

- Architected, designed and implemented a software framework for use in a series of products targeted for storage area networks (SANs)
- Embedded code was written in C++ on an NT platform for a PowerPC (RISC-based) target processor using the VxWorks operating system
- To prove code portability, code was initially integrated on an x86 (Pentium II) based system
- Acted as co-lead on the team and introduced the use of requirements management to effectively control creeping elegance in design and given the challenge of finding a software tool that would provide traceability throughout the development process
- As software technical lead over the channel interface portion of the framework, was responsible for leading four to five junior engineers
- Introduced the use of Unified Modeling Language (UML) in the analysis and design phase of the product to extend code reusability.
- Responsible for evaluating object-oriented analysis/design (OOAD) tools.
