Previously James was a co-founder of the Government Digital Service and Deputy CTO of the UK Government. He was responsible for the technical architecture of the award winning GOV.UK, building the acclaimed team behind it, supporting the delivery of dozens of projects across government and transforming the UK Government’s relationship with open source by “coding in the open.”

Working across government, he helped make the move toward a more user-centric and platform-based architecture for government services. He’s been instrumental in the UK government’s move to use of public cloud, reform of network policy and coordinating the network of senior technology leaders across government.

The technical work he has led has underpinned solutions that have won a variety of awards including the Design Museum’s Design of the Year and a D&AD Black Pencil. The work of GDS was described by O’Reilly Radar as “the default for how government should approach their online efforts in the 21st century”, has inspired similar initiatives around the globe and has been widely celebrated.

James represented the UK government at the W3C, was a member of GitHub’s Customer Advisory Board and has advised numerous startups on scaling and security through a range of accelerator programmes.

Prior to joining the civil service James ran an agency providing websites, business tools and product development to a range of small businesses, charities and entertainment industry clients.
