About me
I’ve spent years working on PCB and embedded hardware projects that need to work beyond just the schematic stage.
A lot of clients come to me after failed prototypes, unstable boards, noise issues, EMI problems, or designs that looked fine but failed during testing,
I handle schematic design, multilayer PCB layout, ESP32/IoT systems, automotive electronics, audio circuits, and production ready Gerber/BOM files using Altium, KiCad, & EasyEDA.
If you already have files, prototypes, or just an idea, send it over and we’ll figure out the best way to move forward.

Great experience working with Ben on my Arduino-based PCB project. He clearly understood the circuit requirements, handled the routing properly, and delivered a clean board design without needing endless back-and-forth revisions. You can tell he knows what he’s doing and approaches the work with confidence.

Very skilled PCB designer. The project involved optimizing an Guiltal Pedal control board layout, including component placement and trace routing, and he handled everything smoothly. The first delivery was already close to the final version, which saved a lot of time. Straightforward communication and solid technical understanding.
