    At the heart of it, we believe in something simple. A better way to do mobile.

    giffgaff is moving from a monolithic application to a microservice based architecture, from fixed infrastructure to the cloud. Did you notice that lower case ‘g’ at the start of the sentence? Great, you’ll need that attention to detail.

    We heart technology

    This is our current tech stack, but we're always looking for new ways to deliver great software to delight our members.
