Final Project

SALUS is a modular product that slides into a soft TPU sports strap and sits flush against your skin, so you almost forget it’s there.

Inside, discreet sensors monitor how much moisture your skin is losing and factors the day’s heat and humidity, turning that into an easy traffic-light score on the companion app .

Soft TPU stubs interlock with matching recesses, giving the strap a breathable, slip-free hold.

Tapered end feeds cleanly through a low-profile loop, allowing quick one-handed cinching and easy release.

The app’s Home, Trends, Alerts and Profile tabs turn raw sensor data into clear hydration scores, charts and personalised settings.

The working prototype sampled sweat every six seconds and triggered a silent haptic alert within 30 seconds of crossing the hydration threshold.

During comfort-and-stability trials of the PLA–TPU mock-up, testers flagged excessive bulk and noticeable strap drift.

Six athletes completed a range of tasks within the UI, praising its clear icons and intuitive layout.

Academic Development

Robotics – Assault-Course Robot (Group)
My group designed, machined and coded a compact robot that could receive commands, climb ramps and extinguish flames. An Arduino-Mega linked IR sensors with the servo powered extendable arm, while PID-driven DC motors delivered the torque for inclined obstacles. Building, debugging and race-timing the robot sharpened my rapid-prototyping, embedded-electronics and control-algorithm skills.

Surface Modelling – CAD Reconstruction
Tasked with replicating an existing artefact, I reverse-engineered a Phase 1 Clone Trooper helmet in SolidWorks, achieving continuous G2 curvature across every surface, draft and parting line. The exercise introduced surface-patch strategies, parametric surfacing and visualisation workflow into my skillset.

Fully rebuilt Clone Trooper helmet, surface-modelled to industry standard for tooling-ready accuracy.

Zebra-stripe analysis confirmed smooth, symmetric G2 curvature, with stripes flowing unbroken across the centre plane and connecting faces.

About Me

A Product Design & Technology postgrad who balances studio time with rugby, endurance runs, and the odd DIY project.

I often focus on IoT, additive manufacturing and AI-enabled products, passions sharpened during my placement at BMI Group, where I prototyped and validated roofing solutions from tiles to integrated solar.

My studies are backed by an Opportunity Scholarship from the MTC, and back at A-level my project was shortlisted for patenting and an Innovations Award.

I find my working style to be responsive, meticulous and comprehensive. I’m currently looking for opportunities so feel free to email or connect on LinkedIn
