With 24 years in IT services Robert Bielecki has gained a strong experience in PKI. He was in charge of the EU Open Source Java library for the electronic signature and worked on the cross-border signature validation in the eIDAS context. This experience allowed him to acquire an extensive knowledge of the related standards and to contribute to ETSI ESI work. He is actively involved in numerous projects, giving him a good vision of the digital trust across the EU. His current professional responsibilities, in Luxtrust, lead him to work on the digital transition of the centralized systems.
