À propos de moi
With 5+ years in PCB design and embedded hardware, I build boards that work beyond the schematic stage.
Clients come to me after failed prototypes, unstable boards, noise issues, EMI problems, or designs that failed during testing.
I specialize in:
Schematic design & multilayer PCB layout
Automotive electronics & audio circuits
ESP32 / IoT embedded systems
Production-ready Gerber files & BOM
I work across Altium Designer, KiCad, and EasyEDA so whatever format you're working in.
Have an idea existing files, or a broken prototype? Send it over let's build something that works.
