Senior Embedded Systems Engineer (IoT & Hardware Design)

Freelance Web Designer • Full-time

Mar 2024 - Present • 2 yrs 2 mos

Specialized in the end-to-end development of custom IoT hardware and embedded systems, with a core focus on the ESP32 ecosystem. I successfully take complex client concepts from the initial block diagram phase through schematic design, multi-layer PCB layout (2 to 4 layers), and full DFM/DFA manufacturing optimization using KiCad and Altium Designer. My day-to-day responsibilities include solving complex hardware challenges such as high-frequency RF impedance matching for WiFi/Bluetooth, architecting ultra-low-power battery management circuits, and integrating advanced industrial sensor arrays. I have successfully delivered production-ready hardware files to clients across the USA and EU, ensuring strict compliance with industry standards and seamless fabricator assembly.
