Six things I was responsible for

Not a gallery of renders. Each sheet states the constraint that made the job hard, the decision that resolved it, and what that decision cost.

Everything here sits at the level of detail already published in my résumé. Geometry, analysis results and design-basis content for nuclear and commercial programmes remain with the organisations that own them.

Pressure vessel general arrangement
B-01 · Nano Nuclear Energy · 2025–present

Micro modular reactor pressure boundary

Pressure-retaining and internal components running at high temperature and multi-MPa. Creep, fatigue, thermal expansion and manufacturability all arguing for different geometry, with ASME III and a licensing case as the referee.

ASME BPVC IIIFirst-of-a-kind

An irradiated assembly glowing blue in a reactor bay
B-02 · Westinghouse Electric Canada · 2023–24

Cobalt-60 in-bay handling equipment

Handling and processing hardware for a nuclear bay. No hand goes in, so every maintenance action has to exist on the drawing before it is ever needed. CSA N285.0, ASME B31.3, ASME Y14.5.

Moving-bed heat exchanger general arrangement
B-03 · Solex Thermal Science · 2024–25

Moving-bed heat exchanger redesign

Sixty per cent of the manufacturing time removed, with structural integrity, thermal duty and continuous-duty reliability all held. None of it bought by accepting a worse machine.

ASME VIII-1CSA B51
Open sheet
Cutaway of a magnetic bearing and stator assembly
B-04 · SKF Group · 2020–22

Maglev bearings & neutron choppers

Rotary magnetic levitation bearings and neutron-chopper assemblies for high-speed compression and wafer manufacturing. A rotor that touches nothing, where the tolerance stack is the product.

Open sheet
Wellhead temperature probe assembly drawing
B-05 · Intelligent Wellhead Systems · 2022–23

Smart lockout & high-pressure wellhead control

Twenty-plus prototypes evaluated in ninety days, then the tolerance-stack and field-failure work that turned a fast learning loop into a product people trust at pressure.

Transmission assembly model
B-06 · Innoson Motors · 2012–19

Truck bodies & vehicle structures

Seven years turning operational requirements into production hardware on a Nigerian assembly line, and building the configuration discipline that let the engineering team grow into it.

The Archive — 2010 to 2022

Product design, assistive technology, urban infrastructure and a makerspace. None of it is what I do now; all of it is why I am able to do it.

I can talk through any of these in detail, within what each programme allows.
