•	Developed new hardware plans including architecture, design and cost estimation.
•	Sourced electrical and electro-mechanical components including reviewing BOMs for cost, leadtime and availability concerns.
•	Provided on-site factory support. Wrote assembly procedures and end-of-line test procedures.
•	Worked with Quality and Software teams to achieve AS9100 certification in 6 months.

Principal Technical Lead

BlackBerry

•	Responsible for design and debug of high-speed interfaces including MIPI D-PHY, USB, and HDMI.  Designed and tested SDIO, UART, PCM and I2S peripheral interfaces.
•	Automated testing of MIPI, I2S, UART, SDIO and PCM interfaces, reducing test time by 80%.
•	Analyzed layout of PCBs and flexes to ensure interface functionality and reduce system noise.  Included stackup and trace geometry to achieve correct impedance.

Digital Design Engineer

Freescale Semiconductor

•	Designed Bluetooth, WLAN, FM and GPS peripherals in Freescale cellular phone platforms.  Created test plans and performed testing.
•	Reviewed customer designs for accuracy and suggested changes to reduce cost and part count.

Platform Design Engineer

Motorola

•	USB subject matter expert. Responsible for testing with USB-IF. Worked with multiple groups to aid their development of USB subsections. Served as mentor for other engineers learning USB.
•	Lead hardware engineer of peripheral sections of iDEN cell phone products. Responsible for scheduling and oversight of testing activities of USB, SD memory card, and SIM interfaces.
•	Worked with factory to solve issues during production and reduce the number of failures.

Senior Electrical Engineer

•	Developed hardware and software for iDEN mini-keyboard product. Optimized firmware to fit it into a smaller, less expensive processor. Transitioned product to manufacturing.
•	Responsible for debug of customer-reported problems in shipping products. Proposed and tested fixes then worked with factory to implement them.
•	Developed software process for the Accessories Group. Met with heads of responsible departments to achieve signoff.

Senior Electrical Engineer, iDEN Accessories

•	Maintained multithreaded, windows-based test framework application used to test Bluetooth lower stack for C-Baseband and Bluetooth System Test projects.
•	Developed tests for and tested Bluetooth baseband implementation using proprietary test development procedure.  Brought test development procedure from concept to reality reducing the time to build tests from several days to 5 minutes.  Provided further automation through PERL scripting.
•	Tested Logical Link and Control Adaptation Protocol layer in Bluetooth COMMPORT product.  Designed tests using Orthogonal Defect Classification methodology and coded in C.

Senior Software Engineer

Sun Microsystems/Encore Computer

•	Designed VME and PCI cards used in large-scale storage products.
•	Performed schematic capture, writing and simulation of programmable logic, part specification, high-speed differential pair layout and debug.
•	Performed debugging and environmental testing of 1GHz Fibre Channel interface necessary to transition product from development to manufacturing.
