I make iPad apps to help people learn and achieve more. I’m the iOS team lead at PSPDFKit and an organiser of the NSLondon meetup.

I’ve worked fully remotely since 2015 and spent time as a digital nomad, but these days I prefer not to travel so much and instead base myself where I can go skiing, ice skating or kitesurfing.

Apps

• Reading app: My simple app to save webpages to read later. Eternally in open beta testing. 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: What’s New in KeyboardKit for iOS 14?
