What David did at Accenture
Accenture is a global professional services firm. David's projects were with global technology clients, which we describe by type rather than by name.
Digital marketing lead
Cross-product SEO strategy, project management and email campaign optimisation for a global search and advertising platform. He built frameworks to grow organic search traffic and make campaign processes more efficient.
Programme management lead
Managed digital development projects and client relationships, onboarded new marketing programmes, and supported advertising sales teams with scaled email, paid media and new business acquisition.
Business analysis and change
Analysed and redesigned business processes to drive feature use for a global video-sharing platform, and designed a cookie compliance framework for a global telecoms company, turning business requirements into technical specifications.

Specify

Build
