Everything I've built.

Designing a safety-critical piston for the propellant pressurisation system of a reusable liquid rocket engine, including the O-ring gland sizing that has to hold at 500–800 psi.

Diagnosed a complete electrical failure on a 450 mm quadcopter to reverse polarity through three sequential elimination checks, identifying burnt MOSFETs from absent reverse current protection.

Hands-on disassembly and reassembly of APU, turbofan, hydraulic, fuel and landing gear systems on decommissioned aircraft, going on to lead a 5-student team.

Led a 10-member rocketry team through the full lifecycle to a live launch reaching 1,700 ft apogee with real-time telemetry, then authored the post-flight failure analysis.

Two roles across a solar race team: carbon fibre bodywork and SEM03 design work, following six iterations of battery casing design validated by FEA under a 20 g load case.

Scratch-built a 600 mm fixed-wing RC aircraft and diagnosed a repeated in-flight structural failure to an aft CG at 60% MAC, correcting to 22% and achieving three consecutive controlled takeoffs.

Led a 4-person team to prototype a myoelectric below-elbow prosthetic arm at £72 per unit, around 95% cheaper than commercial alternatives, in a 24-hour hackathon.

A UWB mesh network for Sheffield's bus system accurate to 17 cm, around 17.5× better than current systems, modelled across 54 receiver nodes with a 2.3-year payback period.

A 3-stage analog signal-conditioning PCB designed in KiCad: amplifier, band-pass filter and comparator. Routed entirely by hand, and it passed ERC and DRC with no functional errors.

Placed 1st in a team drone-building challenge tuning flight stability in BetaFlight, and 4th in a water rocket challenge balancing centre of mass against centre of pressure.
