I have 15 years experience in designing IoT products, specializing in antenna and RF design (cellular/GPS/BLE/WIFi) and regulatory/carrier approvals. Within the design services industry, I've seen hundreds of devices with subpar antenna performance, EMI and EMC issues. Learning the hard way, I know what it takes to design a solid wireless product and pass FCC/PTCRB/ATT/VZW/RED certifications with minimal risk of failure. My main area of expertise is RF design and antenna design. I'm a firm believer of a ounce of prevention is a ton of cure; and getting the antenna, RF and EMI areas of your PCB under control from the beginning will give much less headache when it comes time to test, certify and get to market.

Rapid system prototyping with off the shelf prototyping boards can be accomplished in a short period of time. Having a diverse background in embedded development and IoT, I can provide services based on years of experience with embedded systems in harsh user environments (bus transportation industry, cell phones, hobby grade R/C vehicles, sensors, and medical devices). I am familiar and have used prototyping and breakout boards from many companies including Arduino, Adafruit, Raytac, Microchip, Sparkfun, Nordic nRF52 product line, Digi XBEE3 Cellular, Bosch (IMU), and others. When necessary, custom prototyping PCBs are created with PCB CAD tools. More than three years as lead engineer implementing both hardware and firmware of cellular NB/IoT systems using Digi XBEE3 technology resulted in launch of more than 100 systems now active in the bus transportation industry. Technologies in the product use solar charging, lithium iron batteries, low power implementation, MicroPython programming, watch dog timing, Bluetooth LE control, smart battery management, cellular NB/IoT, and much more. I have excellent knowledge and experience in Software Development Life Cycle (SDLC) and Agile Methodologies. I am flexible to project demands and shifting technologies and requirements. Having a diverse background in embedded development, I can provide services based on years of experience with embedded systems in harsh user environments (cell phones, hobby grade R/C vehicles, sensors, and medical devices). Embedded technologies include concurrent use of pulse width modulation (PWM), analog to digital converters (ADC), digital to analog converters (DAC), Bluetooth LE (BLE), collection algorithms, control algorithms, motion sensing, temperature sensors, light sensors, and much more. I have a BS degree in Engineering with over 25 hours of graduate courses in CS at Johns Hopkins University. I have both designed and managed development of numerous embedded systems including voice (audio) systems for the US Air Force, Motorola Pagers, NEC cell phones, Samsung GSM/GPRS smart phones, and hobby grade (very advanced) radio control vehicles at Traxxas. At Traxxas, receiving seven accepted patents, I provided hands on development and team management for all of the embedded hardware/firmware radio control technologies including spread spectrum radio control links, sensors (GPS, accelerometer, temperature, RPM, etc.), BLE link to iOS/Android phones with several awarded patents and additional patent applications still in process. Rapid development of a medical blue light sensor for an Upwork client connected to an Android App I also developed was completed in 4 weeks with a working prototype demonstratable to investors and end users. Development of a wearable 9DOF high precision motion sensor for an UpWork client illustrates my capabilities for embedded system development, PCB design, and embedded C programming. Thank you and I look forward to working with your company in the very near future. Best regards, Gary DeWitt
