CURRENT DUTIESDeveloped test programs on the VDATS test station, for the APQ-166 Radar Antenna used on the B-52, using LabWindows/CVI.

DUTIESEngineer for the AAR-44B Missile Warning System used on AC-130 gunships.• Tested and analyzed the system’s operational flight programs. Investigated false-alarms and failures-to-detect.• Processed and analyzed sensor and navigation data recorded during flight tests, operational flights, and live-file missile tests.• Worked with contractors L3 Harris Corporation and Georgia Tech Research Institute to improve the operational flight programs.ACCOMPLISHMENTSInstalled data recorders on AC-130W gunships.• Recorded AAR-44 sensor and aircraft navigation data from Ethernet and 1553 busses. Stored the data in Chapter 10 formatted files.• Recovered more than 350 hours of operational flight data from corrupted data files. Repaired time stamps, eliminated duplicate messages, and bridged gaps in the data.Developed procedures to test the AAR-44’s operational flight programs.• Extracted and processed sensor and navigation data from data files recorded during flight tests, operational flights, and live-fire missile tests. Played back the data on the AAR-44 Integrated Support Station to test different versions of the operational flight programs.• Wrote numerous software utilities to expedite data extraction and processing.• Worked with a team to reconfigure the AAR-44 Integrated Support Station so that its throughput was doubled.• Worked with L3 Corporation and Georgia Tech Research Institute to develop hardware and software for the AAR-44, and its ground support equipment.

DUTIESSubject Matter Expert for Power Supplies and Analog Circuits• Develop test programs on the VDATS test station, for analog and digital circuit cards, avionics subsystems, and power supplies, using LabWindows and LASAR.• Design interface test adapters.• Provide technical assistance to other engineers.• Develop quotes for new workload.ACCOMPLISHMENTSProgrammer and Technical Lead•Developed test programs on the VDATS test station, for circuit cards in the ALQ-161A defensive avionics system, for the Signal Data Converter in the Global Positioning System, and for power supplies in the F-15 AIS test station, using LabWindows and LASAR.•Developed test programs on the Advanced Power Supply Tester, using LabWindows., and on the HP-3070 in-circuit test station, using HP-Basic.•Designed interface test adapters for my projects, and for those of other engineers.Project Software Manager• Managed a project to develop test programs on the VDATS test station, for voltage regulators and power supplies in the F-15 AIS, F-16 AIS and B-1B IATE test stations. Managed four to six programmers with a budget of $2.6M.• Managed a project to develop test programs on the HP-3070 in-circuit test station, for circuit cards in the Missile Radar Altimeter Test Assembly. Managed three programmers with a budget of $500K.• Produced or revised CMMI process documents for these projects.• Tracked cost and schedule with EVTAT.• Briefed the squadron supervisor monthly on project status.New Workload• Power Supply Rehost: 1.0M in FY05, $1.6M in FY2007, $2.5M in FY09• Signal Data Converter: 1.3M in FY12 and 13• Set up training courses for squadron personnel.• Participated in a squadron level LEAN event to reorganize its process for developing test programs, with the goal of doubling the squadron’s output.

• Assessed the depot’s capability to perform workload assigned to contractors.• Developed quotes for potential workload.• Developed repair procedures (process orders) for the shop.• Provided engineering support to the avionics production shop.• Maintained test stations.Aug 00 - Jan 01, at Softest Design in San Antonio, TXWorked on a PASCAL application for automatic test equipment used in production tests of commercial products.

Developed software applications in LabVIEW.• Developed a test program for the servo-loop controller for fuel injectors on the MK12 missile.• Upgraded a test program for the T55 fuel control on the CH-47 helicopter.• Developed software for testing actuators on the OH-58 helicopter.• Developed software to emulate the instrument bus for the waveform analyzer in the Honeywell 2600 test station.Dec 97 - Jun 98 at Galactic Technologies in San Antonio, TXWorked on rehosting ATLAS test programs developed for older configurations of the DATSA test station, onto newer configurations, using TYX's PAWS translator.Sep 95 - Feb 96, at Access Research in San Antonio, TXWorked on a Paradox database for logistical and technical data for the F-15 downsized tester.

• Wrote firmware for a bus translator for the F-111 COMETS test station. The translator enabled the COMETS test station to communicate with GPIB instruments, as part of an upgrade to the station. The translator was based on an Intel 80C196KR microcontroller, and the firmware was written in assembly language.• Fixed software deficiencies in the self-test and calibration programs for the B-1B IATE test stations. These programs were in ATLAS and FORTRAN.

• Designed, developed, and integrated the test program and interface test adapter for automated testing of the F-110 jet engine, as part of the ETTAS program. Developed the test program in FORTRAN.• Developed the test requirements for proposed test programs for the J69 and J85 jet engines, also as part of the ETTAS program.

Peace Corp VolunteerTaught math and science at a government secondary school in Bali, Northwest Province.

• Monitored General Electric's, and Textron's development of the reentry vehicle for the MK21 missile, and their development of the test equipment for the reentry vehicle.• Analyzed the results of reliability tests, and aging and surveillance tests, on components of the MK11C and MK12 missiles.
