About

Electronics and hardware design engineer with a background in Computer Engineering. I bridge the gap between electrical schematics and physical product design, delivering complete KiCad PCB layouts alongside precise 3D STEP models for mechanical enclosures.
I ensure all layouts strictly adhere to manufacturer DRC constraints, manage thermal dissipation for power circuits, and optimize board space for ultra-compact applications.
