Portfolio

Client details are anonymized per NDA.

Secure Embedded Linux Platform

Yocto-based distribution with secure boot and production signing.

  • Industrial IIoT device requiring tamper-evident firmware and field update capability
  • Technologies: Yocto Project, U-Boot, OP-TEE, dm-verity, PKCS#11 signing infrastructure

Outcome: platform passed security review and entered production release

Linux Kernel Development

Kernel configuration, device tree enablement, and panic triage.

  • Target kernel in the 6.x LTS series; subsystems covered include USB, SPI, and regulator framework
  • Resolved device tree conflicts blocking bring-up and traced root cause of intermittent kernel panics under load

Outcome: stable mainline-tracking kernel shipped with the product BSP

Zephyr RTOS Board Port

Full board bring-up and driver enablement.

  • STM32-based MCU with I2C sensor array, SPI flash, and UART debug console
  • Enabled board definition, pinmux, DTS, and upstream-compatible driver bindings

Outcome: board merged into project tree; firmware running in production

BSP & Board Bring-up

New hardware enablement and platform integration.

  • NXP i.MX8-based SoC bring-up from cold silicon to running Linux userspace
  • Brought up U-Boot SPL, ATF, and Linux kernel with full peripheral tree

Outcome: time-to-first-boot achieved within engagement milestone; BSP handed off with full documentation
