    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’m a native English speaker. I’ve been working with electronics and developing products for over 25 years. Much of my electronics experience came from working at Microchip (in many different engineering roles). I’ve also developed my own successful products. For the past three years, I’ve been helping others develop their products on upwork. I’m going to help you make a working product, and I’m going to make improvements through the process! I don’t make the above claim lightly. It’s been my experience on every upwork project I’ve had. I work well with others, and can help motivate teams. Through all the product development I’ve done, I’ve created a system for planning and designing working products. This system reduces costs (by reducing mistakes). I frequently make product improvements in: (1) lowering energy usage: important in battery-powered products. (2) increasing performance: increasing sample rates or changing communications protocols. (3) making full use of the microcontroller peripherals to reduce external components. I have experience with many leading-edge technologies, such as: USB/USB-C, Lithium battery charging, LED’s and color mixing, I2S digital audio, analog measurements. I’ve worked with all the common communication busses: USB, RS-232, RS-485, CAN, I2C, SPI, Infrared (with carrier). Work experience Microchip was my first employer after graduating from Arizona State University. I’ve worked at Microchip as a: Test engineer - developing comprehensive test programs to ensure that the chips are free of defects and working as they should. The test programs were all written in assembly. Design engineer - Designing the processor and peripherals. Through this experience, I have a deep knowledge of how processors work (interrupts, clocking, power consumption, and interfacing with peripherals). All validation code was written in assembly language. Silicon validation engineer - Verifying that the first samples of a new product meet the design specification. This was typically assembly language, but sometimes ‘C’ Applications engineer - writing ‘C’ code to help other engineers make use of new features, such as RGB color mixing, IR remote controls, motion sensing, and wireless communication. I’ve worked as an independent developer, developing my own successful products in the areas of computer security and energy-saving pool products. I’ve been working for over 3 years on upwork as an independent developer. I enjoy taking people’s ideas and performance requirements and turning that into a working system. I begin with a block diagram, then schematic, then layout. I also organize the project so that it will be easy to switch to production. I’ve completed over 60 jobs on upwork successfully, and have many great working relationships with my clients. It’s too much to list here, but you are welcome to explore my work history. If you’ve gotten this far in the document, you can see that I’ve been working with electronics (primarily microcontrollers) for the past 25 years. I can do both the hardware and software development. I can also break up the project where I do what services you need. For example, I could do the architecture and hardware design, and you could have someone else do the software. I like to be flexible with my clients and deliver the most value where I can. Building first prototypes 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 PCB’s. 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. We may have all the components in-house to complete your project. Intellectual property protection I’m a professional engineer, and I respect your intellectual property rights. I want to help you protect the intellectual property rights for your product, and also help prevent others from stealing the idea. I mentioned ‘trust’ up above, and this is an area where I can earn your trust by helping protect your product. This could be through patents, trademarks, protected code, …. This is one of the ways that I offer additional value to my clients. If you’re developing a product, I invite you to have an audio call with me (through zoom on upwork). The first call is free, and we can see if I can help you reach your goals in some way.

    Industrial Designer located on the Gold Coast, Australia! Currently, I am employed full-time as an Industrial Designer with a product development company located on the Gold Coast. I'm very experienced with turning people’s ideas into real products that are currently manufactured in China and sold worldwide. 3D CAD skillset: Over the course of my career, I have used a variety of CAD programs, which include: Alibre Design, Solid Works, Solid Edge, and Autodesk Fusion 360. I offer the following types of 3D design: - Single Part - full Assembly designs And I do this using: - Parametric Modelling (this is modelling with known dimension in mind), and - Surface modelling (this style of modelling creates free-flowing organic shapes) Materials: - Plastic Injection mould - CNC - Metal Fabrication Why do I offer my services on Upwork if I am so experienced? I absolutely love this job and honestly cannot get enough of it! I work full time during the day and during the night I work on personal projects, some of which are manufactured in China and sold through various e-commerce stores. It’s also exciting to earn a small amount of coin on the side when the opportunity arises. Why should you choose me over all of the other experienced designers on Upwork? For the same reason, you choose your friends and significant other... trust. To be honest, it should be a good fit between yourself and the designer so both parties get a good outcome, in the end, I bring to you: - Experience - Honesty - Professional attitude - Willingness to create the best design for your buck! - Fast delivery times To ensure you get the same professional service and delivered in the shortest amount of time possible (as you would get with an established brick and mortar design consultancy) I will be following the same tried and proven processes. The Design Process Overview: 1. Protect your idea / intellectual property (IP): 2. Client Brief: Before starting a design it's important for the designer to gain a clear understanding of what the client’s goal/s might be. For example, it’s important to know the manufacturing process before the design starts to ensure the design is created in a way that is optimized for that process. 3. Concept Development: Ideation is often the most exciting stage in the project! The aim is to generate a large number of ideas that can then filter and cut down into the best, most practical or most innovative ones in order to better the product. 4. 3D CAD Design / Modelling: Once the design has been clearly nutted out in the previous stages the 3D stage should be quick to complete. 5. 3D Design Review: Once the design is complete you'll have the chance to review the design and make changes if needed. 6. Sign off: Once you are all happy with the design you will be provided with a file that can be used to manufacture your design. Thanks for reading I hope we can work together and create some really beautiful stuff!
