Hi, I'm Ollie, a Clojure programmer living and working in London for Signal. I've worked with a sprawling collection of technologies over my decade (or so) of programming, ranging from React to Ring. I'm most passionate about developer tooling, text editors and languages.

My free time is mainly occupied by my Neovim Clojure tooling, Conjure. You'll find posts in this blog covering topics such as D3 and React integration as well as building Neovim RPC clients in Rust, it's quite eclectic.

You can find ways to get in touch with me at the bottom of each page.

I hope you find something useful here. Have a great day!
