embedded software
that can't fail.

Bug fixing and software hardening for a medical instrument based on an NXP processor running FreeRTOS. Scope covered both the embedded firmware and the Windows-based GUI front-end, ensuring product robustness ahead of regulatory submission.

Ported a legacy C microcontroller platform to an embedded Linux C++ solution for a transformer temperature-monitoring datalogger and industrial control product. Responsible for driver development, Yocto layer integration, and validation using Google Test.

Led MPU selection and board bring-up for a dual-core A7/M4 STM32MP15x SoC running OpenSTLinux and Yocto. Authored Linux kernel drivers and implemented test routines for all on-board peripherals including 5G modem, Ethernet switch, eMMC, U-Boot, TF-A, Wi-Fi, Bluetooth, and standard serial interfaces.

Second engagement with the HFV team. Created, modified, and repaired test cases for new single- and multi-core semiconductor devices across a range of peripheral interfaces, working within Agile sprints tracked via JIRA and automated through Jenkins CI.

Designed and functionally tested UART and SPI libraries for a cryptographic microcontroller, ensuring correct protocol behaviour and security boundary integrity.

Embedded in the Hardware Functional Verification team, creating and maintaining test cases for new Nordic semiconductor devices across single- and multi-core configurations with Linux-based toolchains and Agile processes.

Ported Realtek drivers using the vendor SDK to an OpenWRT platform on a mesh Wi-Fi extender with Realtek hardware.

Implemented cybersecurity protocols across the company's embedded product range. Conducted threat-vector analysis and FMEA for all products. Designed and implemented a secure U-Boot and kernel using RSA/ECC cryptography with X.509 certificates on an iMX6 platform. Developed a C module validating X.509 public keys in iMX6 OTP fuses to prevent boot of unsigned images. Additional work covered CAN/RS-232/RS-485/Ethernet sensor integration and data-logging on Linux-based loggers.

Developed a firmware update system for an ARM Cortex device via the Serial Wire Debug port and integrated a MEMS microphone on an STM32 platform, as part of a hearing-impaired assistive technology product using Bluetooth Low Energy.

Validated a third-party wireless ISM-band heating control system design. Performed detailed hardware and firmware review and built bespoke validation tooling to verify system operation against specification.

Investigated and resolved Bluetooth connectivity issues in a BLE wrist-strap fitness tracker. Used Frontline Protocol Analyser to diagnose RF-layer problems, then applied firmware fixes to the STM32/nRF8001 platform.

Supported RF compliance certification for wireless street-lighting products and developed new wireless control technologies. Designed a BLE light-detector (Nordic nRF51442) and an infrared/Bluetooth gateway for radio diagnostics. Provided mentoring to junior software engineers.

Designed software and hardware for an automotive interoperability test product. Delivered driver and UI development on ARM Cortex-M4/M7, CAN/LIN bus drivers, an embedded Linux Wi-Fi access point for 5 GHz phone connectivity, and Windows 8 Embedded platform work.
