About me
I’ve spent years working on PCB and Audio device projects that need to work beyond just the schematic stage.
I can turn your concepts into production ready circuits. I design low-noise audio electronics, Bluetooth speaker systems, Eurorack synths, and specialized guitar pedals.
I also engineer complex multilayer PCBs with high-speed differential pairs, custom RF antennas, and complete Gerber files for manufacturing. Let me build your next innovation.
If you already have files, prototypes, or just an idea, send it over and we’ll figure out the best way to move forward.

Technical questions got confident answers that didn’t answer them. Late on it emerged the work was going through an unnamed third party. A second attempt was also mostly unbuildable.
