About me

The GOV.UK One Login app's start screen: the service name, two short lines saying what it is for, and a single green sign-in button held at the foot of the phone.

GDS · One Login & Wallet

Proving who you are, to government, Password protected

Designing the native iOS and Android apps for GOV.UK One Login and Wallet, where identity, trust and accessibility have to work for everyone in the country.

The redesigned My Feeds on desktop and on a phone: named feeds like Chinese influence and Middle East crisis sit side by side as columns on the wide screen, and stack into a single scrollable column on the phone.

BBC Monitoring · My Feeds

All your feeds, at a glance, Password protected

Led the redesign of My Feeds for BBC Monitoring’s global customers, from brief and roadmap through workshops, prototypes and build with an external agency. Now live, with strong early feedback from customers.

Title card for the fandom research: the word Fandom cut out of moving footage, so clips of performers and crowds play through the letterforms.

BBC · Fandom OKR

Fandom: being the voice of the user, Password protected

Prototyped three fan-experience features for the BBC and validated them in weeks. Every participant said the live vote would make shows more engaging.

Three phone screens from the native Live concept: a match page with a Watch live button, the same page with the video playing inline above the live reporting, and a Now playing sheet listing the other live streams for the match.

BBC · Native Live

A native Live experience?, Password protected

Co-led the discovery that reimagined BBC Live as native. The prototypes and research aligned three product roadmaps and joined the BBC Live funding case.
