Software Engineer – Embedded Linux

Owned end-to-end embedded Linux software stack for NXP i.MX91/i.MX93 production gateways, spanning U-Boot, kernel, BSP, and userspace delivered to production with rollback-safe field-update capability.
Built custom Yocto BSP meta-layers from scratch (Scarthgap), including layer configuration, BitBake recipes, .bbappend overrides, kernel kconfig fragments, and device tree modifications via do_patch:append() for board-specific peripheral enablement.
Customized U-Boot for production: authored A/B-aware boot.cmd scripts (compiled with mkimage), configured fw_env.config, tuned environment offsets via menuconfig, and integrated BOOT_ORDER / BOOT_A_LEFT / BOOT_B_LEFT counters for rollback-safe firmware updates.
Delivered RAUC A/B OTA with automatic rollback and LwM2M (Wakaama) FOTA workflows for secure file transfer and remote firmware deployment.
Integrated NXP Wi-Fi/Bluetooth driver packages and firmware blobs into the Yocto image; debugged module load issues and brought up SDIO Wi-Fi/BT and Gigabit Ethernet on the target platform.
Cross-compiled C and Go applications for ARM64 using Yocto's SDK and go-native, packaging them as systemd services with watchdog keepalive, restart policies, and structured journald logging.
Implemented TLS-secured device-to-cloud communication over MQTT (TCP/IP) with RS485-based industrial data acquisition, using size/time-threshold buffering for limited-bandwidth field links. Optimized rootfs via IMAGE_INSTALL trimming, PACKAGE_EXCLUDE, and BAD_RECOMMENDATIONS.
Performed full-stack debugging using GDB, Valgrind, strace, perf, ftrace, journalctl, and tcpdump/Wireshark diagnosed boot-time issues, kernel module load failures, and userspace network bugs in production.
