Experience

Senior Software Engineer, Pocared Diagnostics, Columbus, Ohio, March 2008 to Present. Designed, developed, and supported real-time embedded linux-based in-vitro diagnostic system (using CAN-based robotic controllers, USB-based spectrometer, and fluidics management) with an internationally-distributed development team.

• Created a robust flexible software framework using C/C++ to control/support a multi-vendor hardware/ software solution.

• Developed linux-based C/C++ software simulator/framework for emulating hardware components, enabling development and automated testing of embedded software prior to availability of hardware.

• Developed Matlab-based software for process-control and for manipulation/analysis of optical/spectral data.

Software Engineer, AeroTek [Battelle Memorial Institute], Columbus, Ohio, March 2006 to February 2008. Designed, developed, and supported real-time embedded system using C/C++ on QNX. System controls robotic arms used in a medical diagnostic device.

Implemented TCP socket-based and UDP communication mechanism between host system and robotic controller.

Performed system engineering (requirements derivation/analysis) for urinalysis system. Senior Systems Engineer, Acme Packet, Columbus, Ohio, August 2005 to March 2006. Architected, designed, configured, supported, and diagnosed VoIP/SoIP networks (using SIP, MGCP, and H.323 signaling), focusing on the integration of session border controllers. Senior Consultant, Harvey Nash [AT&T-Network Services], Dublin, Ohio, September 2000 to August 2005. Designed, developed, integrated, tested, deployed, and supported system-level software for real-time embedded prepaid telephony application (coded in C/C++ using GNU SDE on Solaris, Linux, and SCO) using Dialogic IVR/VRU and EXS switching equipment via EXS SwitchKit. Architected, designed, developed, and documented VoIP/SoIP network infrastructure using SIP servlets and session border controllers.

Member of Technical Staff, Ryan International Corp., Columbus, Ohio, April 1999 to September 2000. Developed real-time software for embedded avionics (coded in C and 68000/Coldfire Assembly) in a DO-178 environment implementing TCAS-like collision-avoidance system.
