I’m a dedicated PCB layout engineer with 7+ years of hands-on experience turning complex schematics into production-ready boards especially in power-hungry and noise-sensitive applications. High-efficiency SMPS designs (buck/boost converters, GaN/SiC integrations) and mixed analog/digital circuits, like ADC/op-amp interfaces for sensors and IoT prototypes. I’ve routed dozens of boards where EMI control and thermal management aren’t just checkboxes—they’re what keeps your device reliable from prototype to pilot run.
