About

Senior Embedded Firmware Engineer focused on STM32 bare-metal firmware and Embedded Linux systems, working at the intersection of hardware, low-level software, and real-world production constraints. I design and maintain robust firmware architectures in C, including bootloaders, OTA update mechanisms, custom memory layouts, and linker scripts, always prioritizing reliability, debuggability, and long-term maintainability. My experience includes systems that operate unattended in the field, where fault recovery, safe updates, and deterministic behavior are critical. I’m comfortable debugging complex issues with minimal tooling, often relying on logs, serial communication, and deep understanding of the platform. Core expertise: STM32 bare-metal firmware (startup, memory mapping, peripherals) Bootloaders and OTA update strategies (validation, rollback, recovery) Low-level C/C++ with strict resource constraints Embedded Linux development (cross-compilation, system services, hardware interaction) I work well in remote, international environments, taking full ownership of firmware design and implementation, from architecture to production support.
