06/2013 – today Main activitiies I am currently involved in the web software development on MVC framework based on Perl technologies main Perl pakages: Dancer, DBIx::Class, Template::Toolkit – and Javascript/JQuery name of employer ChumConsulting srl

01/2006 – 05/2013 Main activities I involved in the network and system management of the University G. d’Annunzio of Chieti-Pescara. My main function is to assure the proper functioning of the systems and infrastructures. technologies Main technologies: Firewall: GNU/Linux Bridgewall VLAN aware with IP/MAC accounting through IPFIX/NetFlow collectors ( 35 ∼= 106 ± 40% flow records/day) Blade: Blade Dell with 16 Blade Modules PowerEdge M600, VMware and XEN technology Server Log: A main server log was implemented to centralize switches, routers and servers logs. Backup: A server was implemented with logical volume management for email/web/databases backups with daily snapshots (disk storage system of 6TB). The backup is also stored on tape library (by Open Source software). Captive Portal: for wireless lan area and some laboratories Antispam: in order to improve the antispam service, it was used greylisting system and DCC (Distributed Checksum Clearhouse). Monitoring: in order to improve the monitoring, it was implemented through: – ghosd for notifications on work screen display; – sound alarm (beside server farm); – SMS (for core routers and servers). new building: in order to use the redundant optic fibres, it was adopted RSTP (Rapid Spanning Tree Protocol). name of employer Soabit sr

01/2006 – 05/2013 Other works Mainly: Chimica Farmaceutica laboratory: activated some PCs with 4TB NFS over LVM over raid shared storage with backup system with 4TB over LVM with snapshots Oncology unit: collaboration to create a parsing tool (PDB and Bond data) DKIM: SMTP proxy was implemented with DomainKeys Identified Mail for a high volume MTA (large email sender with 105 emails per day ± 15% HPC: a cluster with 24 nodes (each one 2 processors Xeon 2.4GHz – 4GB) was implemented using Oscar distribution.

10/2004 – 12/2005 Main activities In association with CINECA1 provided for network and server infrastructures and support for the University G. d’Annunzio of Chieti-Pescara under an outsourcing contract. During this period, my main activities were: 1 st level support: an activity with direct contact with user and their problems. 2 nd level support: an online activity in order to resolve users problems. junior systemist: maintenance activity for key servers (Linux based); junior network systemist: maintenance and troubleshooting network/networking problem of the clients. technologies Main tecnologies: Monitoring: a monitoring system was implemented in order to constantly check the status of the core routers and servers and, in case of failure, initiate proper action. Firewall: three key firewalls were implemented from scratch using a combination of bridging and routing firewalling technologies, always built on top of Open Source (GNU/Linux-based) components. Trouble-ticketing: a trouble ticketing system was implemented in order to track user request while, simultaneously distributing these request to network operators. server re-engineering: the whole email infrastructure was completely redesigned and re-implemented. On September 2005, 2072 mailboxes were migrated from the old MBOX format (sendmail based) to a new MDIR format with a MySQL data repository. The migration involved all the user folder (4195) and messages (1,861,934). Soon thereafter, an antivirus service and an antispam service (SpamAssassin based) were added to the platform. network re-engineering: in order to permit the implementation of bandwidth consuming streaming applications, the existing network infrastructure was partially redesigned introducing VLAN technology and VLAN-aware firewall. name of employer PDA Communication srl
