Design that
works in
the real world.

I'm Nixon — a product design engineer who builds at the intersection of hardware, firmware, and human need. My final-year project, O.N.Y.X., is a smart wearable knee rehabilitation brace.

O.N.Y.X.

"Don't just recover. Return."

A smart, wearable knee rehabilitation brace that combines pneumatic compression, thermal therapy, and neural-adaptive feedback — designed to close the gap between clinical physiotherapy and at-home recovery. Born from my own multi-year recovery from a serious knee injury.

O.N.Y.X. uses an Arduino Mega 2560, four GA12-N20 compression motors, dual Peltier thermal modules, and real-time thermistor feedback — all wrapped in a custom CAD-formed shell with a teal/charcoal identity system.

I'm a Product Design Engineering graduate from UWE Bristol, specialising in the full stack of physical product development — from concept and CAD through to electronics, firmware, and clinical considerations.

My work sits at the junction of engineering rigour and human-centred design. I don't just prototype — I defend component choices, navigate regulatory frameworks, and think about how a product reaches the market. O.N.Y.X. is a case study in exactly that.

Outside the lab I play golf (still learning), follow the Premier League closely, and grew up in Knutsford, Cheshire. My brother plays ice hockey for the Manchester Storm, so competitive sport has always been part of how I see the world — and how I think about recovery.

Let's work
together.

I'm actively looking for roles in product design engineering, medical devices, or hardware — ideally somewhere I can keep building things that matter. If that sounds like a fit, get in touch.
