About me
I'm John Mark, a hardware design engineer with deep expertise across the full electronics development lifecycle. My portfolio spans wearable electronics, audio devices, and ESP32-based IoT systems, backed by strong capabilities in PCB layout, 3D mold design, and firmware development. I've delivered designs for military, commercial, and industrial applications, handling everything from sensitive analog front ends to complex digital and mixed-signal architectures. I work fluently with Altium Designer, KiCad, Eagle, and DipTrace, bringing a rigorous, standards-driven approach to every project.
