Multidisciplinary Engineer

Engineering at the
limits of what's
measurable.

From 1nm metrology systems to mass-produced hydrogen components — complex instruments and machines, designed and delivered end-to-end across aerospace, defence, robotics, and clean energy.

What I offer

End-to-end engineering,
across the full stack.

⚙️

Custom Test Systems

Purpose-built test rigs, validation instruments, and automated measurement platforms — from specification through commissioning.

📐

Mechanical Design

CAD, fluid systems, structural design, and production engineering. Designed for manufacture, not just for function.

💻

Software & Control

LabVIEW, Python, PLC, and FPGA development. Real-time data acquisition, control systems, and algorithm development.

🔬

Leak Testing

Accumulation, mass spectrometry, pressure decay, and custom chamber design. Multiple delivered systems across industries, plus a filed patent.

🤖

Automation & Vision

Sensor integration, vision systems, IoT, edge AI, and Industry 4.0 integration. Mechatronics and electro-mechanical systems.

🔭

R&D Projects

Full-cycle research and development — from concept and simulation through prototype, test, and production-ready delivery.

For startups & scale-ups

"Your engineers should be solving your problem, not designing the equipment to measure it. Every week spent on infrastructure is a week not spent on product."

Custom test systems, instrumentation, and development tooling aren't your product — but they are mine. Commission the equipment. Keep your team focused.

Pattern recognition
from a decade at the coalface.

Most engineering advisors have either drifted too far from hands-on work to give credible technical advice, or are too junior to have seen enough. A decade across aerospace, defence, robotics, metrology, and clean energy — at the ground level where real decisions get made and real mistakes get repeated.

Offered management roles many times. Declined every one — to stay close to the craft. The perspective that comes from that choice is different: not theory, not process frameworks, but hard-won experience of what actually works when you're building something that has never been built before.

Engineering organisations make predictable, avoidable mistakes — in how they structure teams, scope projects, choose tools, and decide what to build versus buy. That pattern recognition is available to you.

"The most underrated engineering skill is knowing how to use a procurement process as a design tool. Good design and good procurement strategy are not separate disciplines."
