Employment
  • Freelance Software Developer
    Otogenetics Corporation (via Toptal)
    2015 - PRESENT
    • Create a command line utility for batch processing to adjust the frequency spectra of audio files according to desired parameters.
    • Set up version control repository for project.
    • Document all code and usage notes for the utility.
    Technologies: Matlab
  • Senior Software Engineer
    Alidyne Consulting
    2013 - 2015
    • Prototyped an image processing back-end for a new web application product offering in C++ with OpenCV 2.4. Containerized the processing server using Docker.
    • Developed testing processes for inboard control software of the Sunjammer solar sail project. (www.sunjammermission.com).
    • Created custom test tools for the Sunjammer IPC bus using Python 2.7 and C++.
    • Wrote half of a custom Linux kernel module performing scrubbing of ECC memory, including the user -> kernel space communication code. Kernel code in C. User code in C++.
    • Led a small team of developers in implementing a multi-process simulation system for verification of Sunjammer solar sail deployment and maneuvering algorithms and control code. The simulation system was implemented on Windows in C# and Matlab, with 0MQ 4.0 for IPC.
    Technologies: C, C++, Python, C#, Bash, Make, Sed, OpenCV, Docker, 0MQ, Linux kernel module
  • Contract Software Developer
    Harris Corporation: RF Communications Division (via Yoh Engineering)
    2012 - 2013
    • Contributed significantly to a small development team integrating a third-party Protocol Independent Multicast implementation with Harris-RFCD’s Falcon III network radio platform.
    • Developed an understanding of a complex third-party PIM implementation and integrated PIM code into an existing platform build.
    • Provided analysis and debugging of PIM operation and identified low-level network stack issues.
    • Developed code in C++ and C for QNX 6.4 OS. The build system used GNU Make and GCC.
    Technologies: C++, Make, GCC, QNX, PIM
  • Senior Software Engineer
    The Software Specialists, Inc.
    2010 - 2012
    • Contributed significantly to a small team integrating a third-party NAT implementation with Harris-RFCD’s Falcon III network radio platform.
    • Designed SIP ALG for Falcon III NAT and was integral to its implementation and debugging. Developed with CORBA IDL, C++, and C and deployed on QNX 6.4 OS. Delivered software in time to meet Prime's schedule and with no defects identified.
    • Designed and implemented an autonomous control and navigation system for a prototype Unmanned Sea Vehicle in Java on Windows XP. Created diagnostic tools in Clojure. The prototype system was marketed to and generated much interest from the US Navy, Special Forces, and DARPA.
    • Updated and maintained an embedded web server and diagnostic app for Rockwell-Collins’ RTA-4218 airborne weather RADAR using C, HTML, CSS, JavaScript, and Java. Successfully added many new features while keeping within stringent size and bandwidth requirements.
    • Designed and developed a .NET 3.5 app using WPF with C# and XAML on Windows XP for control of custom ARINC 429 test hardware. The application met or exceeded all requirements during qualification testing and is now used by Rockwell-Collins as a more capable replacement for more expensive hardware.
