- * '''DevelerCompany's IT infrastructure''' - Leveraging
- my earlier work for SiriusCompany, for over 6 years I've
- been continuously growing and restructuring the network,
- the servers and their intricate mesh of services and
- support scripts.  The main server, called {{trinity}},
- contains 1TB of storage and offers file storage, user
- authentication, e-mail, and many web-based services to a
- highly heterogeneous and complex environment comprising
- several versions of Linux, MacOsX and Windows clients.
- Another server, called {{asterisk}}, acts as a VoIP PBX
- and secondary slave for many (but not all) of {{trinity}}'s
- services.

- * '''http://www.fieremostre.it/''' - A cluster of 4 RedHat
- servers, two web frontends and Java appservers and two
- database and filesystem backends with hw SCSI RAID5.
