    I'm fully trained in current electrical engineering practices. I've been doing electronics work for the last couple of years. I specialize in embedded systems; specifically IoT products. I have taken a product from ideation to production including embedded system design, embedded system programming, 3D enclosure modeling and DFM (design for manufacturing). I have worked with manufacturers to make products more robust, cheaper and faster to produce. I work with a lot of startups so I understand the space; tight budget, fast turn-around times & a lot of uncertainty. I can forecast project requirements, timelines and budgets as I've done in the past. ------------------------------------------------------------------------------------------------------ Electronics Experience: low power battery operated devices, microcontrollers, high power switching controls, analog circuits, wireless/bluetooth design, high power LED, product security (encryption), embedded programming C/C++ and peripheral microchip driver creation. I have a lot of experience with non-OS based and lightweight RTOS firmware. ------------------------------------------------------------------------------------------------------ Industrial Design: 3D modeling of enclosures including snaps & press fits, DFM, subassembly design, wire harnesses, low and high volume manufacturing processes (injection molding, resin casting, etc), material I have knowledge of certifications (FCC, UL, CE). ------------------------------------------------------------------------------------------------------ Medical Device In my previous career I did cancer research for 5 years. I am well versed in biological systems, biological tests, testing equipment and non-patient based equipment. I've published multiple peer reviewed papers in this area.

    My education includes a M.S. in Electrical Engineering and a B.S. in Electrical Engineering with a minor in Physics from the Milwaukee School of Engineering. I have experience in a wide variety of electrical engineering disciplines including power electronics, analog circuit design, embedded systems and signal processing. My primary fields of study in my Master’s program were power electronics design/analysis, electronic circuit design/analysis and digital signal processing. One example of a previous job function was at DRS-Power and Control Technologies. The project I worked on was the redesign of all power conversion and distribution systems for the next-generation Navy Nuclear Submarine (Ohio Replacement Program). After 1.5 years at this this position, I lead major start-to-finish designs on five separate, interdisciplinary circuit board designs. These designs required heavy design efforts with power and digital embedded systems including microprocessor, DSP, FPGA and GPP architectures.

    A multi-disciplinary inventor and designer with expertise in quartz crystal and SAW technology, materials science, electronic design, antennas and RF, RFID, embedded firmware and hardware design, and much more. I am a creative and innovative problem solver who is equally comfortable with the big picture or working out the small details in an ongoing project. More recently I have been working with BLDC controllers up to 48V/600W and with charge controller layouts. In December 2021 I retired from IntelliSAW and began only consulting. I am seeking projects between tens of hours and 100 hours or so in scope with availability about 24 hours a week. I have been Florida-based for the past five years, but since July 2021, I am working remote in Belize. This relocation will impact shipping for any hardware support but will not affect my ability to perform design work or design reviews.

    I'm a native English speaker. I have over 20 years of experience working as an embedded engineer. I was one of the designers/architects of the Microchip PIC18 core. I have worked at Microchip as an engineer in test, design, silicon validation, and applications. I have a Bachelor of Science in Electrical Engineering from Arizona State University, where I graduated with cum laude honors. I'm an expert in both hardware and software, so I'm good at tracking down issues. You may think you have a software issue, but it's a hardware issue or vis-a-versa. I enjoy the challenge of finding and fixing problems. I'm motivated by success, and I enjoy what I do. Work with me, and you'll understand. I bill honestly, and sometimes I'm able to solve a problem in a couple hours. No client has ever disputed my hours worked! I've had a couple clients (2/35) who thought I should not be paid for meetings or getting started on a project. These types of situations don't work out, and it's unfortunate because I want to help them, but won't continue to work with them. The best time to involve me in your project is at the beginning. While I architect your system design, I'll make sure that it meets your performance goals, and will reduce component count and cost. For a successful product, it's important to have a robust hardware and software architecture. I solve problems inside a document, and avoid making multiple PCB revisions. Even though I am in Costa Rica, it is easy to ship development boards to me. My home lab includes: - 100 MHz 4-channel oscilloscope (siglent brand) - 8-channel logic analyzer (saleae - this is what I use to analyze digital communication signals: I2C, SPI, UART, ....) - DC supply - benchtop DMM with 1nA current resolution (great for battery-powered devices) - multiple programmers/debuggers (including PICKIT3). The above tools allow me to understand and properly fix problems. If I don't have the exact equipment you are using, I can often wire something up and be able to develop/test code. I may have a processor on hand that can run your code (higher chance if it is a Microchip microcontroller). I am an expert at using MPLAB/MPLABX, but I am also very comfortable in Code Composer Studio (TI MSP430 series), and Microchip/Atmel Studio. During my time on upwork, I have at times taken the role of tutor and mentor - evaluating projects to look for issues, Assisting with documentation reviews, and also documenting projects from scratch. I have a history of identifying design issues before PCB production, saving money and time. Here are some of the technologies that I've worked with successfully in the past: - capacitive touch sensing - USB communication - Bluetooth communication - graphic displays - LED color mixing (precise color control with no flickering)
