About me
I’m an Electronics and Communications Engineer specializing in audio electronics design for guitar pedals, analog circuits, and modular synth hardware. I design PCB layouts and schematics focused on tone, reliability, and manufacturability. My work includes PCB design, SMD/THT conversion, BOM/CPL preparation, and production-ready files for JLCPCB and PCBWay. As a guitarist and musician, I design with real-world sound and usability in mind, turning ideas into build-ready audio hardware.

This was my first endeavor with Fiverr and a commissioned piece. John was very informative with circuits and components. I started with a fairly simple guitar effect circuit. John was punctual and prompt with his replies. Definitely recommend. Thanks again John!
