Summary

Embedded systems engineer with 4.5 years building production firmware for aerospace platforms. Depth across the low-level stack — bus protocols, RTOS, bootloaders, on-target debugging — and the surrounding tooling that turns hardware behavior into something the rest of the org can act on. Comfortable owning a feature from hardware bring-up through field-service recovery.

Experience

Sabbatical Deliberate career break for independent learning and personal development.

Howell Aerospace & Defense · Fort Worth, TX Software Engineer / Embedded

Feb 2021 – Jul 2025

Role: STM32 F4/F7 firmware for aerospace platforms shipping under DO-178B/C. Owned the low-level stack — bus drivers, RTOS integration, on-target debugging — plus the engineering and field-service tooling that surrounded it.
Actions: Built an ARINC 429 driver stack from the ground up with a hardware-abstracted core that supported multiple board variants. Wrote CAN-based bootloader and firmware-recovery (ARINC 825). Built a Python harness QA used to author regression tests, plus C# WPF/MVVM tooling for device configuration and binary retrieval.
Impact: CAN recovery mechanism revived units after failed updates without physical disassembly, eliminating a service category that previously required opening the box. The Python harness scaled from in-engineering use to thousands of QA-authored test files run against production firmware. ARINC 429 stack shipped across the board-variant portfolio.
