·                    Fixed defects reported by the customer, or discovered during testing.

              Hewlett Packard, Communications and Media Solutions

Senior Software Engineer4/2014 - 9/2014

 

·               Fixed problems in C++ software to bulk-load and update LTE Cellular Subscriber Databases.

·               Updated and Maintained Automated Functional Tests in a proprietary version of jmeter.

·               Wrote Linux awk scripts to translate Automated Functional Tests to a different format.

·               Coordinated with four other Engineers on Task Assignments.

              GE Energy, Intelligent Platforms
Senior Software Engineer9/2013 - 10/2013
 

·               Implemented C++ software to convert and download XML rack-configuration files for a proprietary embedded controller/sensor card for monitoring and controlling GE gas- and steam-turbines.

·               Developed firmware directly on the hardware using multi-threaded QNIX real-time Operating System.

·               The sensor software was written to be triply redundant.  The three reported values were “voted” on by the software to ensure that the derived value was accurate.

·               Wrote Automated Unit Tests for this application.

 

Toshiba Global Commerce Solutions
Senior Software Engineer7/2012 - 2/2013
 

·               Designed and implemented new solutions in C++ for the Retail Point of Sale (POS) industry using the Application Client-Server Environment (ACE) for the 4690 Operating System (OS).  These features are special customizations tailored to specific retail-customer’s requirements.

·                    Fixed defects reported by the customer, or discovered during testing.

              Cenoplex
Senior Signaling Engineer9/2011 - 1/2012
 

·               Designed an object-oriented detailed bit-level SS7 decoder for MTP2, MTP3, ISUP and SCCP protocols.  Wrote the decoder in Java on J2EE in a Linux environment.

·               Evaluated the available commercial and open-source ANSI, ITU, and ETSI SS7 software protocol-stack APIs for the development of complete SS7 network nodes capable of fully implementing specification-compliant state machines, and message generation and interpretation, capable of interfacing directly over SS7 links with major tier-one carriers.
