Jonathan is Software Developer at the Guardian. He works on the Membership Acquisition team, who spend most of their time A/B testing new ways of convincing people to support their independent journalism. His passions are A/B test design, creating programs that challenge people's perceptions of themselves and using data analysis/visualisation to persuade and confound.

Prior to joining the Membership Acquisition team, he worked on the Guardian's native Android app and before this, he gained a MEng in Computer Science from the University of Bristol.
