I make apps to help people learn and achieve more. I’m the iOS team lead at PSPDFKit and an organiser of NSLondon.
I’ve worked fully remotely since 2015 and spent time as a digital nomad, but these days I don’t fly and instead base myself where I can go skiing, ice skating or wakeboarding.

Apps
Reading app: My simple app to save webpages to read later. The comfortable reading experience is paramount. This is my main side project.
PDF Viewer: A powerful app to read, search, and annotate PDF documents. I make this with my teammates at PSPDFKit.
Magic Spell: My handy Mac app to check spelling in many files at once. Not actively maintained.
Cambugs: A suite of apps developed with educational psychologists to help teach children to become fluent readers.
Code
KeyboardKit: The easiest way to add comprehensive hardware keyboard control to an iPad or Mac Catalyst app. Read more: The creation of KeyboardKit, What’s new in KeyboardKit for iOS 14? and Migrating KeyboardKit to Swift 6 language mode.
DynamicButtonStack: A UIKit view that lays out buttons in either a column or a row to suit the available space. Read more: Motivation and design details.
