Luke Hartman Luke Hartman

Head of technical services

As the head of technical support, I’m responsible for meeting the needs of our customers throughout the whole end-to-end service inclusive of on-boarding, implementation and support. 

Our focus as a team has been to create a customer-centric operations team whereby we use feedback to deliver greater value in the productDNA services we offer. We encourage for all our members to feedback on our services and welcome this as we revolutionise the way the retail industry operates. 

My experience prior to GS1 UK has been a decade within retail working across multiple disciplines including software delivery, business analysis and operational support. I have diversified in roles from leading world-wide operational support teams to delivering transformation projects in merchandising and buying where the problems of data quality were significant. I have, and continue to use these experiences to my advantage in building and shaping the operations team for the industry-led productDNA service.
