    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)

    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.

    I’m 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 “practical” 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 4x8’ 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 I’m 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 you’re 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, let’s chat and see what happens. Electronics: -Embedded Hardware Design -PCB Circuit Board Design -Low-level Microprocessor Coding, C, C++, Python -Radio Wireless Communications and Certification -Internet of Things, IoT, Mesh Networking, Zigbee -Robotics -Automation -Short Run PCB Assembly -Prototyping and Test Fixtures (in house) -Reverse Engineering, Proprietary Protocols -Testing, Debugging, Product Validation Mechanical: -Solidworks -Autodesk Inventor / Fusion360 -Complex Assembly Design -Process, Testing, and Assembly Fixtures -Injection Molding -High Resolution SLA 3D Printing (in house) -CNC Machining (in house) -Industrial Processing Fixtures -Plastics Fabrication (Tanks, Jigs, Wet Processing, etc.) -Rapid Prototypes and 3D Printing for Industrial Parts -Moving Parts, Gearing, Bearings, etc. Support Services: -Connections with Contract Manufacturers -Crowdfunding, I've raised approx $400k via Kickstarter, Indiegogo -Relationships with Asian and China Manufacturers -Injection Molding & Stamped Metal Parts from Asia -Patent Experience (I hold 7 Patents)

    Electronic Engineer with a keen understanding on micro-controllers and Embedded systems, 6 years experience in the industry. An embedded system is a combination of computer hardware, software, and mechanical parts (sensors, actuators, etc.) that is designed to perform a specific function, often in real-time. These systems require a high degree of predictability and reliability; have a variety of requirements that include size, power, safety, security, cost, and regulation; and typically communicate with one another and interact with the physical world via sensors and actuators in a feedback loop. Embedded systems—such as a microcontroller in a car—are usually not apparent to the user, but are integral for the successful completion of a particular function (such as the control of a braking system or power windows). Embedded systems engineers research, design, develop, test, and troubleshoot embedded systems.
