Iโm Kevin. I design things. Over the last ten years I have taken over twenty commercial products from concept to manufacture while navigating startup challenges along the way. I am โpracticalโ above all else. A team player and easy to communicate with, I am able to take rough concepts and deliver them as working products or prototypes with minimal cost and hassle. My specialty is electronic hardware design, though most projects involve physical or mechanical parts as well. This is my full time job, working from my dedicated workshop near Portland, Oregon. I have in-house capability for most aspects of bringing up new designs and fabricating one-off devices or prototypes. We have high resolution SLA 3D printing (UV resin), a large 4x8โ production CNC machine suitable for plastics and most aluminum, and plenty of bench/floor space for your project. I have relationships with various local machine shops and test labs, so extra support is convenient if needed. I work in Altium Designer for schematic and PCB board layout, and use Solidworks or Autodesk Fusion for physical component design and working with complex physical assemblies. I have designed many injection molded parts, stamped metal parts, etc. Many of my products involve radio so Iโm familiar with the FCC test lab process for both module based radios and custom designs. I have designed Internet of Things IoT products, wireless mesh networking, and low cost proprietary point to point radios. I am intermediate level coding on small 8 to 32 bit microprocessors in C,C++. My code is extremely "human readable" and cleanly documented. I have solid experience with Mircochip PIC processors, Atmel, STM32, and MSP430. I have written several low level handlers for custom board hardware and protocols. If youโre looking for a competent person that is easy and reliable to work with, and who will handle your project as if it were their own, letโs chat and see what happens.

Hello, I'm an Electronics Hardware Design Engineer For Electronics I can help you out in the following cases: 1. You are a company and need to design a new electronic device or any of its sub-circuits from scratch. 2. You are a non-electronics person and want me to design and build you a prototype of an idea you might have in mind. 3. You want me to do a circuit review and suggest improvements to an existing design. 4. You are a hobbyist and are developing a project and need a PCB and schematic designed for it. 5. You are a startup and need a contractor to help you out with a product or its subsystem. Please take a look at some of the projects that I've listed on my portfolio. They have all been designed from scratch. Many of the products I've designed have sold numerous units all around the world so far. For my PCB design I use Altium. Willing to work with another design tool if required. (KiCAD, Eagle, even easyEDA) I have experience in the following areas: 1. Wearables and micro high-density PCB design 2. GaN Based Motor Drivers 3. Solar 4. Lithium-Ion Cells, BMS Systems and their underlying applications 5. Thermoelectric Devices 6. Projects involving popular dev boards like the Raspberry Pi and Arduinos. My main strength is developing products from scratch. I like taking up contracts where I design the schematic, then lay out the PCB, and then solder an initial prototype, test it and ship it to the client. Some of the best selling products that I designed have been Robotic arms, educational shields for Arduino and STM boards and large battery testing equipment. I'm also a fast learner and can handle research projects and projects involving new technology that isn't mainstream yet. Other than work, I'm an adventurer and take part in a lot of hiking, traveling and rock climbing. Have traveled and lived in many different countries. I see Upwork as a chance to connect with people from around the world who have similar entrepreneurial interests. Looking forward to interesting work, meeting interesting clients and building up my portfolio here.
