This my personal site where I host some tools I've made, tutorials I've written and various other things I've experimented with.

Contact me here.


Explaining how to make fun things because, if nothing else, it helps me understand them.


This is a collection of blog posts about various things I've made or thought about. In some cases, I've collected several related posts together or split up a large post into a collection of smaller ones.


I've made various javascript tools, some because I needed them, others just for fun, or just to learn how things work. I've put some of them online in case they are useful to other people, but I can't guarantee that any of them actually work. My SVG optimiser is currently hosted here.


I currently work as a software developer for Oxford Nanopore Technologies, building services to visualise manufacturing data. Before that, I worked freelance, mainly for Khan Academy and Pixar.
