We mostly work on UNIX system level, using what is available on site, meaning all shell flavors, tools like awk, sendmail or Tcl, languages like Perl, lua, C or even Fole and XGF. We combine these into various script models using a standard approach or by finite state models, specialising on process automation in a very broad sense.  We've done projects on system administration, website maintenance and dynamic building, document control, change management and source control, authentication services and encryption, database design, etc.  All standard OS platforms can be tackled ranging from HPUX, AIX and Solaris to various Linux flavours or Wintel.  And we're not afraid taking on the occasional mainframe project. We've served a multitude of clients in past (KBC, Rank Xerox, HP, Honda, Swift, BNP Paribas Fortis, Delhaize, etc.).
