À propos de moi
PCB design and embedded systems engineer with 5+ years' experience specializing in multi-layer, boards for UAV, IoT, industrial, and consumer products. I work in Altium Designer and KiCad, from schematic capture through DFM-ready manufacturing files, with expertise in signal integrity, power integrity, and EMI/EMC mitigation for HDMI, USB 3.2, CAN-FD, and MIPI CSI-2. I also write firmware in C/C++ for STM32 and ESP32, so I can validate the hardware I design. Recent work includes a flight controller, a 45A ESC, a USB 3.2 hub, and a wireless audio interface. Let's build your board right.
