In the early 90's Fred got involved with Unix through his employer and because of that became involved with NLUUG.
Since the beginning of this century Fred has been active as a freelance infrastructure architect, project manager and Unis system administrator. During this period most Unix variants have been touched, like BSD, SystemV and Linux.
Fred's NLUUG involvement began in 1992, both as a regular member and in various other roles.
* Member/Chair of of the programme committee of various NLUUG conferences.
* Member of the organisation of all SANE conferences.
* NLUUG Boardmember from 2000 till 2006

A few years ago the NLUUG structure has changed and the board has chosen for continuity with a fixed programcommittee. Since June 2023 Fred has taken on the position of programchair.
