    I have 40 years of experience in business and technology related industries. My experience in the Pharmaceutical industry alone exceeds 25 years. I have been responsible for the creation of a number of business solutions from small business to worldwide corporations. I have dealt with a range of clients from senior executives to front line clerks. Every project I have been involved in has been a success. During the past 30 years, I have guided my corporation through years of success as an independent consultant, a task that is not achieved by many in the industry. Recently, I have developed a web based application for the Victims’ Advocates in the Surprise Police department. The system maintains interactions with the advocates and their clients. The application utilizes MySQL databases as well as PHP technologies to provide a very robust tool for the advocates. As part of a volunteer project, I have adapted Raspberry Pi devices to work with a VOIP product (Mumble) to help the Civil Air Patrol more efficiently communicate with their staff during mission critical events. I created the entire server structure to process all user management as well as the setup of the Mumble server. Again, MySQL, PHP and python were some of the tools utilized. I have revolutionized several pharmaceutical companies to properly manage their sales and promotional marketing budgets during the last 25 years. The last development introduced new procedures through extensive change management so they could manage a budget approaching 1 billion dollars. The resultant technology solution that I implemented managed over 3500 projects and affected over 350 end users in the past year. The system managed both production schedules as well as budgets. In addition, it interfaced directly with SAP to tightly integrate all financial data as well as purchase activity. I designed and developed a web-based system to manage all of the Field Sales promotional spending for over 4000 sales representatives. The funds and budgets were integrated into the budget management system and thus help increase sales revenues by timely use of budget dollars. I have worked with one of the leading genetic research branches of a large pharmaceutical company for over 15 years. The tasks accomplished have been in a wide range of disciplines including laboratory system development, legal tracking, research budget management and product sales support and web site development. I have designed and developed a system to manage all of the purchases of bulk cement for the world’s third largest cement manufacturer (at that time) for sales in the United States. The system integrated all the sales with the general accounting system and produced all the accounts receivable documents. I also provided technical support to their staff and installed and maintained various network configurations in extreme work environments. I have worked various other industries throughout the United States. I have worked in the governmental arena (Federal and State), a private world-wide consultant firm, a computer manufacture’s software development area and a wide variety of private industries. Summary - Developed online web based Victims Assistance application utilizing MySQL/PHP technologies for the city of Surprise Police Department. Developed and trained users with web based online calendar scheduling system for the cities of Glendale, Surprise and Avondale for Crisis Response teams within city Fire Departments. Designed and developed budget management systems for Pharmaceutical Marketing Operations and Finance for 1 billion dollar budgets. Designed and developed Pharmaceutical Field Sales web system to manage promotional budgets for over 4000 sales representatives. Provided training for all skill levels from end user to executive management. Designed and installed the entire network for a California bio-technology company utilizing network switches and MS Servers over 10/100 based cabling. Provided on-site technical support for the first 10 years for a California bio-technology company including all MS Office products as well as locally developed database systems. Utilized a wide array of advanced technology skills to implement projects during 35 years of project development. Lead project manager for many of the projects involving interdepartmental disciplines. Designed, created and developed applications utilizing Oracle database technology for over 20 years. Created sales system for one of the world's largest cement producers for all of their US operations. Managed multiple on-site technical analysts on contract to Ford Motor Co. Worked with biotech research companies, especially in the areas of DNA research. Provided technical support with Genesis, Vision, GradePro and IEP systems for local teacher at Tolleson School District.

    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.

    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.
