Hi, I'm Jonny Buchanan, a programmer / web developer from Northern Ireland, who lives in Australia.

This is my personal website, where I keeps things I've made, and notes about things I've learned, am learning or have been thinking about, somewhere which isn't social media, a GitHub repository or a Gist.

Writing

• til - things I've learned
• notes - notes on various topics
