Summary
Sean Yang is a senior embedded software engineer based in New Zealand with 11 years of professional experience building firmware and networking systems across x86, ARM and MIPS platforms. He has deep expertise in bootloaders, Linux kernel and driver development, rootfs/build systems (Buildroot/OpenEmbedded/OpenWrt), and secure networking stacks including VPN, Netfilter and crypto. His background spans consumer and telecom domains—set-top boxes, xDSL, 3G/LTE and DVB—demonstrating a track record of shipping multi-core, multithreaded solutions and conditional access systems. Comfortable from assembly to Java, he combines low-level performance tuning with system-level integration and has repeatedly delivered production-ready images using BusyBox and custom rootfs. An often-unsung strength is his cross-architecture portability work, translating platform-specific constraints into maintainable, reusable code across diverse SoCs.
