    I'm fully trained in current electrical engineering practices. I've been doing electronics work for the last couple of years. I specialize in embedded systems; specifically IoT products. I have taken a product from ideation to production including embedded system design, embedded system programming, 3D enclosure modeling and DFM (design for manufacturing). I have worked with manufacturers to make products more robust, cheaper and faster to produce. I work with a lot of startups so I understand the space; tight budget, fast turn-around times & a lot of uncertainty. I can forecast project requirements, timelines and budgets as I've done in the past. ------------------------------------------------------------------------------------------------------ Electronics Experience: low power battery operated devices, microcontrollers, high power switching controls, analog circuits, wireless/bluetooth design, high power LED, product security (encryption), embedded programming C/C++ and peripheral microchip driver creation. I have a lot of experience with non-OS based and lightweight RTOS firmware. ------------------------------------------------------------------------------------------------------ Industrial Design: 3D modeling of enclosures including snaps & press fits, DFM, subassembly design, wire harnesses, low and high volume manufacturing processes (injection molding, resin casting, etc), material I have knowledge of certifications (FCC, UL, CE). ------------------------------------------------------------------------------------------------------ Medical Device In my previous career I did cancer research for 5 years. I am well versed in biological systems, biological tests, testing equipment and non-patient based equipment. I've published multiple peer reviewed papers in this area.

    I graduated from an accredited university with a bachelor's degree in electrical engineering with a GPA of 3.65. Since that point I now have over 10 years experience in various fields of engineering ranging from electric drives to security systems. My primary focus has been with embedded systems and PCB design. I have used numerous controllers in past designs however the most popular with my clients has been the arduino and various versions of it. Also the teensy has been a popular choice lately. I use Eagle Cad to design PCB's and can design up to four layers although two layers will suffice for most projects. I also have have experience with various IOT modules such as the laird bl652, esp8266, and the particle. If you have any questions please contact me.

    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.

    I received a Bachelor of Science in Mechanical Engineering with Honors from the University of South Florida. While there I led the computer science team in a NASA sponsored rocketry competition to autonomously identify three colored tarps from an altitude of nearly 1 mile. I focus on embedded systems software and hardware design projects. Specifically consumer and industrial products. I am the President of MicroType Engineering, INC, a product design and production firm. We recently expanded into a full electronics assembly house, allowing us to go from design to prototype to production. The core focus in everything I do is ensuring that the client is 100% satisfied. Please look at the feedback from past jobs as proof of this commitment.

    For the last 20 years, I have designed many electronics projects involving defining requirements, system architecture, part selection, schematic design, PCB layout, and firmware/software programming. Designing electronics and embedded systems can be extremely complicated. Unfortunately, it can be difficult to communicate clearly even about simple topics. One of my greatest emphases is effective and honest communication. This always requires careful listening and sometimes the willingness to say "I don't understand. Will you please explain this to me?" and the honesty to say, when necessary, "I don't know, but let me go figure out the answer." I live to face new challenges, solve new problems, and learn new things. Let me bring my experience and enthusiasm to bear on your project.

    After 10 years in aerospace industry, I've a lot of expertise in embedded electronics development, production and suppliers management and quality. I'm able to guide you and develop for you from needs to mass production. I have a lot of knowledge in real time constraints, high temperatures electronics , power supplies (digital control )and embedded software. During these years, I had been also a quality supplier manager. I audited more than 100 companies. Last two years I developed an electronic and software from scratch for an innovative 3D printer. I like making complex into simple by having a global view of the system or organisation. I accept NDA and that is why I don't show much on my profile or my website.

At A Glance: Embedded Systems

Computer, electrical, and mechanical systems run nearly all aspects of our lives and are constantly being developed and created for new and novel uses. Many of the systems that have been developed don’t require fully functional general systems and instead rely on smaller embedded systems, which are small electronic systems that can operate on less power in more extreme environmental ranges. Embedded systems can vary from the relatively simple to the highly complex, but no matter how advanced they are, working with current systems or developing new ones is a difficult task. If you are looking to implement embedded systems into your business or project, or need to work with embedded systems that are already interacting with your business, then working with an embedded systems specialist is key to a successful operation.

Embedded systems specialists can hail from several different backgrounds, from engineers to computer scientists and electronics technicians. A freelance embedded systems specialist’s experience can come from working with microcontrollers or microprocessors found in a variety of systems, such as traffic lights, MP3 players, watches, and various avionic technologies. Embedded systems specialists can leverage this expertise to help you modify and optimize current embedded systems for your business needs and uses. Specialists can also help you find resources to train, design, or even create custom systems for your use or distribution. However you leverage the talents and skills of a freelance specialist, you can be comfortable knowing it will be an effective and powerful tool for you and your business.
