Jasper
Habit-building hydroponic garden consumer electronics
2022 - Present
I developed Jasper from concept to commercial production with two friends as a passion project. It ties together my love of plants, hardware prototyping, and building great products that empower others.
My role as Engineering Lead has focussed on modelling and rapidly prototyping new features, then translating them through DFMA to production alongside our factory partners.
DryGro
Enzyme extraction for F&B industry from plants in climate-insecure regions
2016 - 2024
I joined an Oxford spin-out to bring a new and promising crop, Lemna, to the world. We built two green-field facilities in rural Kenya, grew the team from 2 to 30, and worked with dozens of research partners and suppliers to develop the crop production and biorefining systems needed to realise our goal. I served as CTO and head of engineering.
PrototypeFluids
Accessible microfluidics for hobbyist and academic biotech researchers
2015 - 2016
My masters thesis - designed and built a custom PCB-mounted microfluidics product for automating microfluidic workflows. I worked with the London Centre for Nanotechnology, Imperial College’s Synthetic Biology Laboratory, and the London Biohackspace during product discovery, prototyping, and validation.
CARV
AI ski coach wearable (getcarv.com)
2015
Starting from a breadboard prototype, I took on the product design and hardware development alongside our embedded systems & electronics engineer. We spent 2 months at HAX accelerator in Shenzhen rapid prototyping and working with factories to bring the product to life.
The product had a successful Kickstarter, raising £275k via 1,200+ backers, with over 20,000 units sold since.
DIY Laser Cutter
Large-format homebuilt laser cutter
2013
To expand my prototyping skills and home workshop, I built a custom CO2 laser cutter in my garage.
Dimensions: 1x1m
Laser: 40W CO2, liquid cooled
Motors: NEMA23
Controller: GRBLshield + Arduino Uno + Universal G-code Sender
Compiler: Inkscape + Gcodetools extension
Single Point Incremental Forming
Thesis paper on a CNC rapid sheet metal forming technique
2012
During my final year of undergraduate studies I completed a research project into CNC incremental forming of sheet metal. I designed & turned new tool shapes and characterised their forming limits and effect on surface finish.

DFMA Teardown
A 1-day rapid teardown and reassembly of an SK410
2016 - 2024
During the first week of my masters me and 3 classmates got our hands dirty in the shop disassembling, analysing, and then building a physical exploded view of Shark Pro Steam & Spray SK410 Series floor cleaner.
This model now lives in Europro’s European office.
Liquid Desiccant Solar Air Conditioning System
Research job building and commissioning an experimental LDAC system
2011
One summer spent in the sun building and commissioning a novel AC system in the Queen’s Solar Calorimetry Lab. It was a deep dive into psychrometrics and building & troubleshooting fluid systems.
You can read an overview paper on the system and its performance here: Performance Evaluation of a Liquid Desiccant Solar Air Conditioning System
DIY Keyboard
Soldered and programmed a series of split column-staggered keyboards
2021 - 2022
Modern keyboards are still modelled after the typewriter. I tested and built several newer designs to improve the ergonomics and efficiency of my time at the computer.
Here’s a little guide I made on Notion:
