Natick, MA

• Qualified and validated test hardware and software prior to production release.
• Test software modules controlled automated electro-mechanical test equipment hardware for functional testing camera UUT
• Supervised team execution of test HW and SW qualification plans resulting in quality product helping company achieve 52% (2017) and 10% (2018) growth rates
• Coordinated test HW and SW qualifications with New Product Introduction manager; d/FMEA and DFM input, led up to 5 qualifications at a time
• Analyzed qualification log data and devised key performance reports to present to product team - resulting in possible test HW, test SW, and/or product changes
• Support for both sustaining products/fixtures and NPI concurrently

Nashua, NH

• Developed test code and documentation from military requirements, using NI TestStand
• Test code was for use in conjunction with electro-mechanical fixtures to validate that RF power supply was functioning as expected
• Software development life cycle (SDLC) included requirements phase, integration validation and verification, regression testing, and release to US Air Force base where it would be used by technical operators
• Led implementation of code/peer review process where team would complete and review a Potential Problem Log, allowing for earlier detection of software bugs and issues with documentation development process

Waltham, MA

• Created a Visual Instrument, using LabView, to communicate between user and robot: sent and received commands/feedback
• Performed various radio antenna communication tests, including characterization and measuring channel power output to determine whether a circular or vertical transmitting antenna was more efficient in broadcasting.
• Measured gain (dB) of amplifiers at different frequencies (MHz), using a radio transmitter, a NiMH battery, and a spectrum analyzer
• Built audio, video, and data communication cable harnesses as well as test fixtures for testing robot
• Created wiring documentation, a test procedure, and a more comprehensive schematic, using Visio, for the Operator Control Panel of robot
• Using this new documentation as a reference, built an OCP from ordered parts

Boston, MA

Through Northeastern University's Department of Electrical and Computer Engineering, assisted a PhD Candidate in Ferrite Plating research. In addition to data collection, developed a device to move magnets along the x-axis in order to manipulate electromagnetic waves. Used AutoCad to help design device and then researched cost and materials based on.

Lexington, MA

• Updated test procedures for an infrared camera for military use, using Microsoft Word 2007 and Visio 2007
• Troubleshot infrared cameras (Thermal Weapon Sights) in rework department that failed at test points in assembly and testing process to determine and report the corrective action

Gloucester, MA

• Tested fixtures for RF power systems in the production sub-assembly department by following test procedures and edited as needed
• Converted schematics and PC Board layouts from old to new software package
• Learned how to solder and built, tested, and documented a 3, 2 way 4 KW 60 MHz combiner
