Hardware × Software Engineer

James Harcourt

I design and build embedded systems and health-tech — from low-cost IoT glucose monitors to solar trackers and iOS companion apps. Bringing hardware, firmware and clean interfaces together into things people can actually use.

Current obsession: turning messy sensor work into calm little devices.

Selected projects

A mix of hardware, firmware and apps I've built end-to-end.

Featured · IoT Health2025–26

GlucoBit

A low-cost IoT system for non-invasive glucose visualisation. A CircuitPython device pulls live readings from the Dexcom cloud over WiFi, renders them on a colour LCD, and fires audible + LED alarms on lows — paired with a native iOS companion app over Bluetooth.

About

I'm an engineer who likes to live at the boundary between hardware and software. Most of my work starts with a real-world problem — like making glucose data glanceable for someone living with diabetes — and follows it all the way down: schematic and PCB, firmware on the metal, the cloud calls, and the app in your hand.

I care about systems that are reliable, low-costand genuinely usable — not just demos. I'm comfortable across embedded CircuitPython and C++, native iOS in Swift, and the web. I also enjoy the hands-on side of things: soldering, 3D printing, and designing PCBs.
