Design and development of embedded systems for industrial applications• hardware design in Altium and software development in C for an auto-darkening filter lens prototype using an ARM Cortex M23-based microcontroller• development of RTOS for a powered air-purifying respirator system utilising an Xtensa microprocessor• provided design support for the embedded system component of a supplied air respirator prototype• maintenance of embedded software for gas monitor system running on RISC-based PIC MCUs• setting up a continuous integration system and Docker-based toolchain for embedded projects listed above to allow faster development time

Programming in C for embedded Linux systems:• driver development for switching (Marvell), Power over Ethernet, and PHY chipsets• platform hardware and pluggables (copper and fibre) support• feature development on AlliedWare Plus, Allied Telesis' operating system• fixing issues relative to release cycle (working with external development centres or manufacturer FAEs)

Development and maintenance of test automation systems and validation tools required for delivering high-value features on radio networks• interoperability protocol compliance• system performance under various conditions (load, fading and network impairment)• network migration capability• regression of cadence software. These systems required functionality from various tools I maintained such as: protocol simulators, voice transcoders using network capture, Python libraries, and Wireshark packet dissectors.

Please refer to the description for the 'Test Analyst' role.

Test automation system for wireless MIMO links on the Mimomax Tornado radio platform. The test automation system was deployed on Jenkins, and consisted of automated tests written using PHPUnit and Selenium test frameworks. The automation test suite performed functional (QoS, RF modulation, bandwidth configuration, header-payload compression, VLAN, firewall, etc) and performance (latency and data rate) tests under point-to-point and point-to-multipoint link topologies.
