Hardware & software engineer / Dublin, Ireland
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.

Hardware, firmware and apps, built end to end.
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.
A KiCad plugin and CLI that links component datasheets, generates priced bills of materials, and verifies parts against DigiKey. Built to take the repetitive work out of preparing a PCB.
An interactive Boolean logic workbench. Draw gate circuits, build expressions, generate truth tables, and practise logic problems directly in the browser.
A browser-based Python IDE for Leaving Certificate Computer Science practice. Run code locally with Pyodide and check answers against exam marking rubrics.
Play videos as live truecolour ASCII art in the terminal, with audio. Frames are streamed and converted in real time using Python, yt-dlp, and ffmpeg.
An iOS app to support diabetes management and data visualisation
A dual-axis solar tracking system in C++, sensing light direction and driving motors to keep a panel aligned with the sun for maximum yield. Hands-on embedded control, sensors and actuation.
A thrust vector controlled model rocket with telemetry and flight data analysis.
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-cost and usable. 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.
Work, internships, education and things learned along the way.
