Hire the Best Hardware Prototyping Specialists in Washington

I am an RF and Embedded Systems Engineer with 10+ years of experience developing wireless products, custom hardware, and embedded firmware from concept to production. I specialize in RF circuit design, multilayer PCB layout, antenna integration, and firmware development for IoT and connected devices. My experience spans WiFi, Bluetooth, LoRa, Sub-GHz, LTE, GNSS, and mixed-signal systems. I have worked on battery-powered products, industrial IoT devices, wireless sensors, and custom embedded platforms, focusing on performance, manufacturability, and regulatory readiness.

Whether you need a complete product design or support for a specific hardware or firmware challenge, I can help turn your ideas into working products.

I help teams design and ship connected hardware products, whether you are building a new venture or expanding an existing product line. From high-level system architecture through schematic design, PCB layout, embedded firmware, cloud integration, and production readiness, I support the full product lifecycle. I specialize in commercial embedded and connected systems that must be reliable, scalable, and ready for real-world deployment from day one. With over six years of experience designing electronic products and the firmware that drives them, I work across hardware, embedded systems, and cloud infrastructure. My work includes custom electronics, production-ready PCB design, firmware architecture, and enclosure development for commercial products. Much of my background is in IoT environmental sensing and control systems, but my experience extends across embedded platforms and connected devices more broadly. I have five years of experience working within the AWS ecosystem, designing systems that leverage MQTT, AWS IoT Core, Lambda, ECS, RDS, and related services for secure data collection, fleet management, and operational reporting. I have extensive experience with Espressif’s ESP32 platform along with STM32 and other embedded systems, delivering products ranging from wireless sensing devices and lab equipment access control to industrial and autonomous systems. I frequently work on systems where reliability is critical. This includes products that must operate continuously in the field, integrate with safety-related infrastructure, or meet strict operational requirements. I design with long-term reliability, serviceability, and regulatory considerations in mind, including awareness of certification pathways such as FCC, CE, UL, and related compliance processes. In addition to system design, I maintain in-house rapid prototyping capabilities that allow hardware to move quickly from concept to tested prototype. This includes PCB prototyping, embedded firmware bring-up, and mechanical prototyping using both additive and subtractive fabrication methods with engineering-grade materials, along with small-batch electronics assembly and validation. These capabilities enable faster iteration cycles, early hardware validation, and smoother transitions into manufacturing. My focus is on building systems that are not only functional, but robust, maintainable, and ready for real-world deployment and production.

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.
