Raimilson Carlos J.
End-to-End Product Development | 20+ Years of Experience
I specialize in turning ideas into real, manufacturable products — from napkin sketch to functional prototype to mass production. With over 20 years of experience in electronics, mechanical design, and prototyping, I help entrepreneurs and startups develop smart devices and physical products with a clear path to manufacturing. I’ve led full-cycle developments in consumer electronics, medical devices, and industrial hardware, delivering products that are already in production worldwide. We operate globally, with offices in China, Brazil, Italy, Canada, and the USA, giving us direct access to cost-effective prototyping, certified suppliers, and reliable manufacturing partners. What I Offer: • Product design with DFM and IP-ready documentation • Embedded electronics (STM32, ESP32, BLE, UWB, sensors) • PCB layout and firmware development • 3D CAD modeling and functional prototyping • Small-batch assembly and BOM sourcing • Global logistics and supplier coordination I already support customers in Europe, North America, and the Middle East, and can provide references upon request. Let’s bring your product to life — I don’t just design, I deliver
