• Designed our first product branded “Terminus”. Capabilities included cellular communication, Embedded Python, SPI, GPIO, UART and automotive compatible switching power supply.
• Designed a line of Plug-In cellular terminals that enabled our customers to embed cellular communications into their PC boards and circumvent the costly ($20k+ GSM/UMTS, $50k+ LTE) carrier certification process..
• Designed a Linux SBC that incorporated the Janus Plug-in series radios with standard PC interfaces including 802.3 10/100Ethernet, USB 2.0 Host and Device ports, RS-232 Serial ports, RS-485, CAN and GPIO (Digital and.
• Designed a Cortex-M4 microprocessor based product for applications that required embedded standalone C application but did not require the power of a Linux based O/S. The product was designed around the Janus Plug-in.
• Hardware designs including GSM/EDGE/UMTS/HSPA+/CDMA/EVDO/LTE Modules, GPS, Cortex/ARM9/8051 Micro-Processors, CPLDs, Switching Power Supplies.
• Experience with Embedded Cellular Modules From Telit Wireless, Nokia, Siemens and Sony Ericsson.

• Custom solutions requiring Customer interaction, Creation of Design Specification and Multi-Phased Proposals.
• Execution of Mutli-Phased Projects requiring project management to meet customer exceptions.
• Hardware designs including GSM/CDMA/Satellite Modules, GPS, Micro-Processors, CPLDs, Switching Power Supplies.
• Experience with Embedded Cellular Modules From Nokia, Siemens and Sony Ericsson.
• Design experience with Ethernet, USB, UART, I2C and SPI.

• Stratum Timing Products)
• Design of Stratum 4 multiple reference timing modules used in SONET fiber optic networking equipment.
• Responsible for PLL loop design to meet Telcordia MTIE and TDEV specification during reference phase/frequency events.
• Specified factory test and measurement specifications required to meet documented product specifications.
• Maintained design/factory documentation within a ISO 9001 system.
• CPLD/FPGA Synchronous logic design and simulation. Including inclusion of Asynchronous signals into a common clock domain.

• VCXO / VCO oscillator development.
• First project consisted of isolating a VCO design issue that resulted in a shipping delinquency of 50k pieces. Worked with end customer to solve temperature performance issue and implement a design change to get.
• Developed VCO products for use in a Fortune 500 telecommunications company’s cable services distribution equipment.
• Design tools: Pspice, OrCAD.
• Software Development using Visual Basic to create custom automated test software to characterize oscillator performance over all operating conditions (Supply, Temperature, Control Voltage and Output Load).
