Responsible for electrical engineering design, testing and documentation of pre-FDA medical robot. Performing motion studies using a high-speed camera, machine vision and Python scripting. Modeling magnetic fields.

Designing cutting edge medical devices for startup customers. Specializing in low-power, Bluetooth products and smart implants.

Senior Principal Electrical Engineer responsible for a medical sensor used during total knee arthroplasty, knee replacement, surgery. The sensor uses Bluetooth to send load data to the surgeon in order to ensure a balanced replacement.Responsible for:• Designed and supported a medical sensor used to measure implant loading during total knee arthroplasty surgery. Sensor used capacitive sensing and Bluetooth Low Energy to send load data to the surgeon.• Created company's electrical engineering process.¬• Led company-wide electrical engineering, including US and South Korea-based teams.• Worked with regulatory test labs and agencies in other countries to get product acceptance. Included IEC 60601-1-2, UL and FCC.• Developed verification and validation plans and tested prototypes for FDA submission.• Negotiated with supplier to extend expiration date on batteries potentially saving $6M in scrap.• Developed tool to determine antenna efficiency requirement for early prototypes. Plotted actual measurements using Python.

• Worked with inventors and entrepreneurs to turn their ideas into manufacturable products.• Designed and prototyped products to customer specifications.• Products included Bluetooth wearables and IoT, PWM motor control, LED lighting and solar charging of lithium-polymer batteries.

• Technical lead of hardware development team with two electrical engineers, two mechanical engineers and a PCB designer in a startup with IoT products in the marine and aerospace markets. Product used PWM to drive high-current outputs for motor and lighting control. Communication interfaces were ethernet and RS-485.• 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.

• 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.

• 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.

• 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.

• 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.

• 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.

• 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.
