My next job came in 2006, when I contracted with eWorldCom Kft., a small VoIP company, developing call center software based on Asterisk. My job was to create a small base system for this software, while managing the old, Ubuntu based ones. For the new version, we targeted Gentoo Linux because of its possible small size, and performance reasons. The company since then fusioned with Virtual Call Center Kft. You may reach my ex-bosses (Tamás Jalsovszky and Szabolcs Tóth) there, altough I don’t know any of their new contacts.
The job that followed was with Lufthansa Systems Hungary in 2007, where I became the member of a large team supporting and administering several thousand servers, mostly based on Red Hat Enterprise Linux and SUSE Enterprise Linux. There I mastered cluster technologies (Heartbeat 2 and Red Hat Cluster), SAN, iSCSI and NFS based storages, Apache httpd and Tomcat web servers, administration of MySQL and Oracle 10g Databases, Bacula based backup, Windows 2003 Server and Windows Server 2008 (both standalone and cluster) with Active Directory, Group Policy, Microsoft Exchange Server 2005 and Microsoft SQL Server 2005, Xen Open Source virtualization, Citrix XenServer and XenApp, VMware ESXi and vSphere, Nagios monitoring (and monitoring in general), and last, but not least, Linux hardening (SELinux, firewalls of different kinds, fighting application security issues). My boss was László Kiss-Kalló, who can be reached on +36 (30) 429-9483.
All this knowledge came in very handy, when I went to Brokernet Group Zrt. in 2010. The IT infrastructure was in a very bad shape there, and our job was to rebuild most of it from scratch. We utilized Debian GNU/Linux servers (both standalone and Heartbeat 2 clusters), Apache httpd web servers, Exim+Courier IMAP for mailing, Bacula based backup, MySQL and PostgreSQL database servers, Oracle Databases (both 10g and 11g), Microsoft SQL Servers (both 2005 and 2008), Windows 2003 Server and Windows Server 2008 (both standalone and clusters), Active Directory, Group Policy, centralised ESET NOD32 antivirus, Windows cluster based file server with AD backend, WSUS, OTRS::ITSM helpdesk, Zabbix based monitoring, virtualization with Citrix XenServer, IT security solutions with SonicWall appliances, SELinux, Snort and iptables, Perl for system administration scripts, and PHP and the Symfony 2 framework for internal web development. Although much has changed in this list since then, it was my best experience so far. You can contact Attila Balogh on +36 (30) 924-8179.

In my free time, I wander in forests, take pictures, and sometimes manipulate them with the GIMP. Sometimes I write short novels using LibreOffice. I am also developing some software in C. When I’m not in the mood for writing, I go and check out the news on several technical areas, mostly IT and engineering, or give a try to a new programming language in the name of “why not?”. Currently I’m experimenting with Python.
Although I don’t plan to change my workplace right now, when I do so, I look for firms that can develop my skills and give me financial stability through an interesting job.
