Leadership Team

James Harris

Chief Executive Officer

James is founder and CEO of Elgin and one.network. He is a technologist and entrepreneur with a passion for solving problems with simple but innovative solutions. Frustrated by the lack of reliable information about road closures on sat-navs, James set about addressing that gap in 2012 with a solution that is now used widely by highway authorities across the UK. Elgin’s platform has evolved into an advanced traffic management and smart mobility solution which is transforming the way authorities manage their highway networks and communicate with road users.

Rui Silva

Chief Technology Officer

Rui is Elgin’s CTO and lead architect. He has been a partner in the business since 2013 and previously held senior roles at SAPO (Portugal Telecom) and Safira.
