Embedded systems architecture and software development for safety-critical medical robotics devices.

• Designed and implemented MISRA C++ compliant communications firmware on Zynq Ultrascale+ using FreeRTOS, facilitating communications between the Nvidia Jetson Orin, MPSoC and KUKA robot.
• Designed multi-core shared memory architecture for inter-core communication on Zynq Ultrascale+ MPSoC.
• Designed and implemented interfaces to KUKA robotics systems in compliance with KUKA communication documentation, including safety-critical connections.
• Architected a safety-critical supervisory FSM on ARM Cortex-R5 lockstep core.
• Designed and implemented an immediate-mode embedded UI in C++ using Dear ImGui on Nvidia Jetson.
• Deployed YOLOv5 PyTorch model for real-time edge inference on Nvidia Jetson Orin AGX, including selecting the hardware platform.
• Established cross-platform testing strategy: Unity for embedded, GTest for Linux application, and pytest for ML application.
• Built a custom minimal Jetson Linux OS image using Nvidia tooling and QEMU, including writing systemd services and bash scripts.
• Produced documentation in compliance with IEC 62304 and IEC 60601.
• Built CI/CD pipelines for both embedded code and Docker image generation integrated with automated testing and deployment.

Developed a new thermal model generation process for variable frequency drives.

• Designed and built an automated IGBT thermal data collection system including custom PCB, embedded C++ firmware, and 3D-printed mechanical components.
• Wrote a C# .NET program to process IGBT thermal data into VFD thermal models, incorporating an ML algorithm, WPF UI and SQL Server database.
• Mentored a junior engineer through the developed tooling and test procedure.

Rotational graduate programme across Power Electronics, ECAD, and Tech Support departments.

• Power Electronics: Developed .NET test automation suite; wrote optimised C# thermal data processing algorithm reducing run time by 8 hours; produced documentation to IEC 61800.
• ECAD: Completed PCB layout for a family of boards; introduced Git-based distributed version control for PCB design; established internal KiCAD workflow.
• Tech Support: Built Python web-scraping and data processing tool using Qt and Selenium.

Summer placements in Electronics, Tech Support and Embedded Elevator teams as part of the E3 Academy scholarship scheme.

• Simulated control circuits in SIMetrix and carried out EMC testing.
• Specified and implemented a suite of automated tests for elevator drives in IEC 61131-3 Structured Text on a PLC.
