I spend most of my time turning messy problems into real physical products — medical devices, consumer hardware, defence equipment, and the tooling that makes them possible. I care about how things are made, not just how they look.
A few things I've learned to value after shipping products across medtech, consumer hardware, and defence.
I prototype as soon as possible — foam, 3D prints, soft tooling — because CAD only tells part of the story.
I spend a lot of time thinking about draft angles, tolerances, and how a part will be moulded, machined, or assembled.
FEA and tolerance stacks help me sleep at night, but I always try to back them up with real testing.
ISO 14971, FDA design controls, and IEC 60601 aren't checkboxes — they shape how safe products get built.
Some of my best design feedback has come from mould shops and machinists who know what actually works.
Good documentation is how a design survives hand-off. I try to leave things clearer than I found them.
A few projects I've been lucky to work on across medtech, consumer hardware, and industrial systems.
Managed the full V&V program of an FDA-approved battery-powered radiation dosimetry device. Identified & resolved critical mechanical issues including springs, cyclic loads, and bending stress using a data driven approach. Managed design controls, biocompatibility selection, and supported 510(k) documentation.
Developed plastic injection-moulded components for a Class II respiratory spacer system compatible with universal jet and spray nebulisers to achieve ISO and IEC standards. Focused on reliability, biocompatibility, and user comfort.
Developed the front fascia of a smart ticket vending machine deployed across the US and Canada, incorporating coin receptors, LCD display, anti-vandalism systems, and UV protection verified against MIL-STD & environmental tests.
Designed lab equipment used in radioactive material handling. Designed a gear-transmission system used for tele-operation in a radioactive hot cell. Performed tolerance stack-up analysis & material selections for critical mechanical systems used in corrosive and chemically volatile environments
If you're working on something interesting in medtech, hardware, or manufacturing, I'd love to hear about it. You can reach me by email or connect on LinkedIn.
