Later I worked for software companies like "Sopra/Stéria", customers like Robertshaw ( process control ), swisscom ( Swiss Telecom ), SBB ( Swiss federal railway company ), "caisse d'épargne" ( banking and security software ), UBS ( infrastructure management software for websphere ), project management for security projects like SSO ( single SignOn for the AIX Platform ) but also in the Internet area in the mid-ninetieth with daneel.com or computer.fr.
