    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.

    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)

    An Industrial Designer and Electronics Engineer with extensive expertise in developing electronic devices from the scratch, including PCB boards designing, creating 3D products, and prototyping hardware. I have successfully finished number of projects involving both industrial micro-controllers (STM32, ESP32, Raspberry Pie) and small computer micro controller as well as their communication protocols. I have over five years of expertise with CAD, renderings, and prototyping as part of my Design for Manufacturing (DFM) background. I offer services for Product Design, which include 3D designing, rendering, prototyping, and basic sketching. I utilize several advanced software and tools that includes KiCAD, Eagle, Simple EDA, MATLAB, SolidWorks, Altium Designer. I also have experience in SolidWorks, Abaqus, and ANSYS to undertake Thermodynamic computation, Finite Element Analysis (FEA), and Computational Fluid Dynamics (CFD) analysis. CAD modelling: SolidWorks, Fusion360, AutoCAD, and CREO software My Services: 1. Design of digital circuits. 2. Design of Analogue Circuits. 3. Microcontrollers such as the Raspberry Pi, STM32, and ESP32. 4. FPGA. 5. Circuits for Power Supplies 6. Multilayer PCB design specialist, producing boards from PCBA and JLCPCB (I source components from companies like Texas Instruments, Digi key, and Mouser). 7. PCB manufacturing file generation, such as BOM, GERBER, and CPL. What you will get? • Properly implanted and thoroughly tested PCB board with flawlessly functioning parts. • Effective and reasonably priced services for product design and prototype. My Specialties: 1. I have extensive expertise in developing mechanical and electrical systems and have successfully delivered multiple projects 2. I can develop custom modules tailored to specific requirement instead of using pre-built modules available in market. I create custom modules that enable my clients to manufacture their boards from a single, unique factory eliminating the need to purchase modules and components from various manufacturers. 3. I have Hardware Lab that is completely furnished with all the tools required, including soldering stations, Digital meters, power supplies, and also 3D printer. I have all the necessary tools, including 3D printers, and offer all prototyping services. 5. I have collaborated with several multinational corporations, offering them a range of engineering services. Availability: I am available 24/7 only a text message away, and prepared to take on new assignments and projects from our clients.
