About me
Hi, I'm Ethan, a Product Designer and Electronics Engineer helping startups and companies turn ideas into manufacturable products. I specialize in industrial design, mechanical design, enclosures, prototyping, and DFM using SolidWorks, Fusion 360, AutoCAD, Creo, and KeyShot. I also develop embedded systems, custom PCBs, and firmware with Arduino, ESP32, and STM32 using KiCad, Altium Designer, Proteus, EasyEDA, and LTspice. I support BOM sourcing, Gerber generation, and production with JLCPCB and PCBWay. I value clear communication, reliable delivery, and engineering that is built to scale.

As a Product Designer and Electronics Engineer, I help startups, inventors, and businesses transform concepts into manufacturable products. My work covers industrial design, mechanical engineering, 3D CAD modeling, enclosure design, prototyping, design optimization, and production-ready documentation. I develop embedded systems, custom PCBs, firmware, and IoT solutions using Arduino, ESP32, and STM32 platforms. I create schematics, PCB layouts, BOMs, and manufacturing files while coordinating production with JLCPCB and PCBWay. Using SolidWorks, Fusion 360, AutoCAD, Creo, KiCad, Altium Designer, Proteus, and EasyEDA, I have delivered solutions across consumer electronics, industrial equipment, smart devices, automation systems, and custom hardware products.

Ethan did a fantastic job designing a complicated networked LED control board for our project given a detailed specification document. He additionally took time to do some detailed revisions for a small additional fee after we discovered an issue with our original specifications. I recommend working with him and may collaborate with him again in the future!
