Cambridge-trained engineer building across disciplines
I design and ship hardware, software, and ML. Usually the same project needs all three.
I design PCBs, firmware, developer tools, desktop apps, and edge AI systems. Most of it lives where those overlap, like running a model on a microcontroller, or a CLI that reads your git history.

About Me
I build across the hardware/software line — PCB design and firmware for embedded systems, plus CLI tools, desktop apps, and AI experiments.
The interesting problems live at the intersections: deploying ML on microcontrollers, building developer tools that read your git history, or designing a USB-C power analyzer from scratch.

A few things I've built recently
Open hardware you can buy, AI tools that run offline, and apps I actually use day to day.
Spark Analyzer
Open-source USB-C PD analyzer and programmable supply
Set the exact voltage, watch the live current draw, and log it, instead of poking at a charger and hoping.
View DetailsTracer
Ultra-low-power motion tracker designed for wearables
A month of motion tracking from a coin cell, small enough to actually build into a wearable.
View Detailscodekeep
Terminal deckbuilder that turns commit history into gameplay
Your real commit streak from the last 90 days becomes starting HP — the more you shipped, the longer you survive.
View Detailsollamacode
Offline coding agent that acts on files and commands directly
Runs entirely on your machine through Ollama: no API key, no code leaving your laptop.
