Bukeni Tete Waruzi Beck is a field worker from the Democratic Republic of the Congo (Eastern DRC), and director and founder of AJEDI-Ka/Projet Enfants Soldats, an organization that helps child soldiers and children affected by armed conflict in the Uvira region of South-Kivu. He has worked as a researcher on child soldiers in the great lakes region and is trained as an economist, having earning his degree from the Evangelical University in Africa based in Bukavu.

Beck created the AJEDI-Ka/PES in 1998, when the DRC's civil war was at its most intense due to the involvement of various foreign actors such as Rwanda, Uganda, and Burundi, motivated in part by the exploitation of natural resources. AJEDI-Ka's priorities since its inception have been identifying children most at risk of abduction of voluntary recruitment into armed forces, advocating for the cessation of the use of children as combatants by belligerents, demobilizing and reintegrating child soldiers and preventing further recruitment of these children in Uvira and eastern DRC as a whole. In order to achieve these goals, Beck spearheaded the creation of the village structures of Monitoring and Reporting on child rights violations in areas where active combat is frequent.

In addition to this grassroots work, Beck also undertakes research; one of these projects has culminated in a forthcoming essay entitled "Child Soldiers: A Comparative Study on the Traditional Ritual Initiations of Soldiering and the Cultural Attitudes of Social Reintegration."
