Product design engineer taking consumer hardware from concept to mass production.
I’m a product design engineer at Amazon, working on ambient AI wearables and on Ring and Blink cameras and doorbells at volumes over ten million units. My job is the physical product: the mechanical architecture, packing RF, optics, PCBA, thermal and battery into an industrial design, and then holding tolerances and yield all the way through EVT, DVT and mass production on the factory floor.
Now
Jan 2024 – presentProduct Design Engineer, Amazon
I work on consumer hardware: ambient AI wearables and smart home security cameras. I was the first product design engineer at Bee.computer, an ambient AI wearable startup acquired by Amazon, and I lead product design for 2K and 4K Ring and Blink cameras and doorbells shipping at more than ten million units.
- Own the mechanical architecture and drive integration across RF, optics, PCBA, thermal, battery and industrial design.
- Apply DFM and DFA, GD&T to ASME Y14.5, and statistical tolerance analysis to hit quality targets without slowing the schedule.
- Run FEA on critical features and sub-systems to converge on robust design margins.
- Support EVT and DVT builds on site at contract manufacturers in Vietnam, Malaysia and China.
- Camera-specific work: lens and sensor stack integration, module packaging, thermal interfaces, and sealing and ingress protection for outdoor use.
These programmes are confidential, so there are no detail pages for them. The projects below are earlier work I can show in full.
Earlier work
10 projectsDrug delivery devices, research and vehicle design from 2018–2022, documented in full. Most of the devices were developed at Mediscient Devices; their internal mechanisms are confidential and several have patents pending, so those pages show what the devices do and what I contributed rather than how the mechanism works.
Wearable Bolus Injector
A smart, low-cost wearable insulin injector for developing markets, with a purely mechanical delivery mechanism and a Bluetooth data logger.
0.5 mL Needle Safety Device
A passive needle safety device for high-viscosity depot drugs, designed around Lanreotide and the enlarged hands of acromegaly patients.
Fixed Dose Pen
A pen injector for low-viscosity drugs like Teriparatide, with the fewest parts of any comparable device and a dose counter built into the plunger rod.
Variable Dose Pen
A reusable dial-a-dose pen injector for drugs like insulin, where the dose changes day to day.
Autoinjector
A single-use autoinjector with an integrated needle safety sleeve, taking the clinic visit out of subcutaneous, intramuscular and intradermal injections.
1 mL PFS Needle Safety Device
A three-part retrofit that adds passive needle safety to glass pre-filled syringes without touching an existing filling line.
Intradermal Injectors
Prototype work on intradermal delivery using a short, shallow needle array.
Microneedle Platform for Wearable Drug Delivery
Hollow 3D printed microneedle patches meant to replace the indwelling needles used by commercial wearable injectors.
All-Terrain Vehicle Research Group
Head of design for a university team building a genuinely tough all-terrain vehicle: 12 kg lighter, generatively designed wheel assemblies, and a driver cage validated by explicit dynamics.
Covid-19 Analytics
A modified SEIR model of the Covid-19 outbreak in India, run across six lockdown strategies to find the one that minimises deaths without shutting the economy indefinitely.
About
I’m a product design engineer at Amazon in San Francisco, working on consumer hardware — ambient AI wearables and Ring and Blink security cameras and doorbells. I take products from concept through to mass production: the mechanical architecture, integrating RF, optics, PCBA, thermal and battery into an industrial design, and then the unglamorous part that decides whether a product actually ships — tolerance stacks, DFM, and EVT and DVT builds on the floor at contract manufacturers in Asia.
Enthusiastic about design, cars, martial arts and chess.
