    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)

    I have over 22 years of experience working and consulting for tech companies in Silicon Valley. Every technical challenge that I had overcome assured me that with the right frame of mind, I could accomplish anything. Engineering is also my hobby, and I have been doing it since before high school. I was born with a soldering iron in one hand and writing code with the other. I designed the hardware for over 100 projects, most of them being sold today. Some notable ones are Snapchat Spectacles (designed most of the electronics and PCB layout), Thornwave Labs' Bluetooth DC Power Meter (PowerMon) and all the other projects on the webpage, various RF modules (RN-171, RN4020, RN52), and development boards designed while working at Microchip. I also created production testers, lots of C/C++ programming, and firmware design. What I can do for you? --------------------------- High Level: project management, research. I am very experienced with hardware design and firmware, which allows me to integrate them more efficiently. Hardware: circuit design, component selection, electrical schematic, PCB payout. I am using Altium Designer. I will provide you with everything you need to go to manufacturing: Gerber files, NC drill, pick and place, assembly diagrams, 3D prints, 3D STEP model, and electrical schematics as well as offer support after the project is completed. I have experience with analog and digital design, RF, high-speed design, microcontrollers, highly complex boards, LCDs. I can run Spice simulations as well. I worked with various technologies and protocols: SPI, I2C, UART, USB, CAN, RS-485, Ethernet, Bluetooth, WiFi, and so on. Prototyping: I will manufacture the prototypes at a much lower cost than average. Over the years, I have developed working relationships with manufacturers in China, hence the cost-saving. I also have a lot of equipment: multimeters, oscilloscope, logic analyzer, vector network analyzer, USB protocol analyzer, power supplies, digital electronic load, soldering equipment, computers, and so on... Certifications: I can assist and oversee the certification process for FCC, IC, and others. Firmware development: I have 24+ years of experience coding in C/C++ and 20 years of firmware development. I can architect and develop your firmware from the ground up. I am exceptionally versed in the ARM Cortex line of microcontrollers: STM32 and Nordic. I will provide you with production-quality firmware. I know the ST and the Nordic microcontrollers like the back of my hand. I can get firmware done very quickly and efficiently for these chips. Software development: Basic tools running in Linux/Windows/Mac, basic GUIs. I can develop all the software tools you need for debugging, testing, and manufacturing. Manufacturing: If your project reaches this phase, I can offer contract manufacturing services. I will be delivering your finished product, ready to sell. The rate I displayed is an average number. It can vary up or down based on the complexity of the project. My rate reflects the experience and knowledge I have. I am good at what I do. Also, keep in mind that I will not bill you for hours like lawyers do for the time they spend in the shower thinking about the project. I will bill you only for the hours I spend advancing the project in a meaningful way.

    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.

    Hello. I am an electronic engineer. And if you're reading this, you at least know about electronics too. So I will tell you about my capabilities as a colleague to a colleague. I've come a long way, and at each step I've improved. I am constantly studying and learning new things. I have realized many projects, from the simplest ones like "microcontroller, button and LED" to the most complex ones, like the complex automation of a large factory. A tiny fraction of my work is in my portfolio (constantly updated). Now I am a full-time freelancer. I am focused on the development of consumer and industrial electronics. When it comes to electronic devices, I do full-cycle development: 1 - circuit design (Altium, Eagle, KiCAD) 2 - modeling of electrical circuits ( LTSpice, TinaTI, etc.) 3 - firmware development (STM8, STM32, ATmega, MSP430) 4 - development of enclosures and other structural elements (Autocad, SolidWorks) 5 - PCB development (Altium, Eagle, KiCAD) 6 - work with suppliers of components (I use dozens of suppliers, from the giants like DigiKey to small local ones) 7 - manufacturing of prototypes (my lab is quite equipped for this) 8 - supporting the customer as long as necessary. I'm lucky - my work is also my hobby. And I would be glad if my experience and my capabilities were useful to you. Sincerely, Dmytro.

    🏆 Top Rated Product Developer ( I've developed my own products || I'm now helping others on the Upwork platform ) 🏠 I have a Small Home Laboratory to develop/debug prototype boards for your product 💭 I'm a native English speaker My name is Stephen, and I have 25+ years in product development, including 13 years at Microchip in roles like Test Engineer, Design Engineer, Silicon Validation, and Applications Engineer. I specialize in developing products from concept to working systems. I can handle both hardware and software or work flexibly on specific areas like architecture and hardware design. I’ve developed two successful products: (1) KEYKatcher hardware keylogger – A device plugged into a PS/2 keyboard port to record and play keystrokes. It was popular among parents for monitoring children's computer use, with tens of thousands sold. Sales declined as PS/2 ports became obsolete (2) TightWatt pool timer – An intelligent controller for swimming pool motors, featuring a year-round algorithm. It was awarded a patent and gained national distribution. Through all the product development, I’ve created a system for planning and designing working products. This system reduces costs ( by reducing mistakes ). I frequently make product improvements in 1️⃣ Lowering energy usage: important in battery-powered products 2️⃣ Increasing performance: increasing sample rates or changing communications protocols 3️⃣ Lowering product cost: making full use of the microcontroller peripherals to reduce external components I have completed more than 70 projects on Upwork but to check my capabilities or skills, you can check out the following projects: ➡️ Hardware Prototype Design for Plant Monitor Product using ESP-32 ➡️ Microchip ATtiny202 Code Development ➡️ Energy Storage Monitoring System ➡️ BM83 Bluetooth Application Schematic ➡️ Embedded System with PIC Microcontroller & Accelerometer ➡️ PCB Power Usage Optimization ➡️ TI MSP430 Development Additional Skills: ➕ Leading-edge technologies such as USB/USB-C, Lithium Battery Charging, LED and Color Mixing, I2S Digital Audio, and Analog Measurements ➕ Common Communication Busses: USB, RS-232, RS-485, CAN, I2C, SPI, Infrared ( with carrier ) As mentioned above, I have a small home laboratory where I have all the tools I need to develop/debug prototype boards for your product. This includes: ⚙️ Multiple programmers for Microchip, Atmel, and TI parts ⚙️ Logic analyzers to quickly find issues with communication busses such as I2C, SPI, UART, I2S, …. ⚙️ A “power profiler” with picoAmp range ( yes, picoAmp, a trillionth of an Ampere ) for power optimization of low-power products ⚙️ A reflow oven for assembling prototype PCBs ⚙️ Inspection equipment for verifying PCB assembly ⚙️ A fellow Upwork contractor is available to do the physical assembly work. She works at a much lower rate than me and has the patience to hand-populate / hand-solder prototype boards Some electronic inventory is on hand. I may have all the components in-house to complete your project Feel free to contact me through UpWork. Best Regards, Stephen
