Six months building the engineering tool for a grain-cooling chiller line: vapour-compression cycle modelling against real refrigerant property data, psychrometric and load calculations, compressor and heat-exchanger selection, and the sizing reports an engineer has to sign. Shipped as a web platform with a native mobile client for use on site.

Led development of AI-driven ADAS features — surround-view 3D visualization, obstacle rendering and an in-cabin natural-language voice interface — on Renesas R-Car hardware. Owned performance across the CUDA, OpenGL ES and machine-learning boundary, plus technical direction and mentoring for the feature team.

Designed and reviewed GPU-programming evaluation tasks used to train and benchmark frontier language models. Authored problem statements with explicit inputs, constraints and objective acceptance criteria, produced validated reference solutions, and peer-reviewed other engineers' submissions for technical correctness and completeness.

Pioneered the company's OCT imaging analysis platform: GPU-accelerated deep learning for retinal layer segmentation, real-time 3D reconstruction in OpenGL, and the Qt clinical application clinicians used day to day. Included two international onsite engagements.

Machine-vision inspection systems, industrial control integration and robotics — currency authentication, oil-seal inspection, a 600 kg material-handling robot and a bipedal radiation-survey robot for nuclear plant use.

Designed and built domestic and industrial robots, and ran the technical training side of the business alongside it — robotics courses, seminars and hands-on workshops. The full build path stayed in house: schematic design, PCB layout and etching, assembly and bring-up, so trainees followed a board from drawing to working hardware rather than starting from a kit.

Designed power, earthing and distribution transformers and reactors to customer spec up to 5 MVA / 33 kV — winding and core-cutting instructions, oil and cooling calculations, radiator and conservator selection, bills of material, and the AutoCAD drawings production built from, to IS and BS standards.
