I’m an embedded-Linux engineer with ~1 year of hands-on work across multiple SoCs and boards (NXP i.MX91, NXP i.MX93, BeagleBone Black, ST STM32MP157, Raspberry Pi 4/5). I build reproducible Linux images, bring up device drivers and services, and make headless/remote GUIs usable for real labs. My focus is practical: get the board booted, networked, and productive—then automate it so the next build is one command.
