About

I build technology that bridges hardware, firmware, and software into world-class products. With experience spanning embedded systems, firmware development, hardware bring-up, and secure platforms, I’ve delivered at scale on products like Amazon Echo and Apollo SoCs at Ambiq. Today, as Head of Device Engineering at Tohands, I lead the complete lifecycle — from hardware design and firmware, to production readiness and cross-functional team execution. My unique skillset spans: • Embedded & Firmware Engineering — BSP, Linux Kernel, Bootloader, secureBoot, device drivers. • Hardware Integration — board bring-up, validation, production test automation. • Productization — aligning firmware with factory processes, scaling devices from prototype to production. • Leadership & Mentorship — building processes, coaching teams, and bridging engineering with business goals. I thrive at the intersection of engineering depth and product ownership, with the long-term goal of shaping teams that deliver devices at global scale.
