<p>I am <strongitemprop="name">Gergely Polonkai</strong> (sometimes referred to as <spanitemprop="nickname">W00d5t0ck</span> or <spanitemprop="nickname">Polesz</span>), a <strongitemprop="jobTitle">software developer, systems engineer and administrator</strong>. I was born on <strongitemprop="birthDate">7 March, 1983</strong> in Budapest, Hungary. I spent my life moving here-and-there in the country, and finally settled in <strongitemprop="address"itemscopeitemtype="http://schema.org/Address"><spanitemprop="locality">Tura</span></strong>. Although I have already found my mate for life, I am <strong>single</strong> yet (living in a common-law marriage), being the proud father of a son.</p>
<p>You can reach me on <strongitemprop="email">gergely<spanclass="at-obfuscation"></span>polonkai.eu</strong>, or by phone on <strongitemprop="telephone">+36 (30) 7375-706</strong>. I fluently speak and write <strong>English</strong> and <strong>Hungarian</strong>.</p>
<p>I have <strong>graduated in 2001</strong> from <em>Táncsics Mihály Szakközépiskola, Szakiskola és Kollégium</em>, an architecture high school based in Veszprém, Hungary. There, I learned about <strong>electricity and elevators</strong>, while getting my feet wet in the area of systems engineering. Together with some teachers, we developed <strong class="keyword" title="network building">the IT infrastructure of the school, building it from scratch</strong> with <strongclass="keyword">Windows XP</strong> based clients, and <strongclass="keyword">Debian GNU/Linux</strong> servers with <strongclass="keyword">Squid proxy</strong>, an <strongclass="keyword">Apache httpd</strong> web server, <strongclass="keyword">Exim</strong>+<strongclass="keyword">Courier IMAP</strong> based internal mailing and a <strongclass="keyword">Samba file server</strong>. Meanwhile, I have created the school’s first <strongclass="keyword" title="web development">web page</strong> using <strongclass="keyword">Perl CGI</strong>, and it’s replacement later in <strongclass="keyword">PHP</strong>. Although I did that as a student, I consider it as my first job. You can contact <strong>Imre Pataki</strong> on +36 (20) 970-5830 if you need more information.</p>
<p>My first contract was made in <strong>2002</strong> with <strong>GaTeS Group Kft.</strong>, a Budapest based <strong>ISP</strong> that served Internet connection to a large warren. I have mastered Linux based <strong class="keyword" title="firewalls">firewalling and routing</strong> there using <strongclass="keyword noupper">iptables</strong>, and <strongclass="keyword" title="QoS">tc for QoS</strong>. I have also created a <strong>web page</strong> for the company using <strongclass="keyword">PHP</strong> and <strongclass="keyword" title="MySQL database development">MySQL</strong>. My only contact for this company was Ákos Szabó, whose phone number is not working any more.</p>
<p>After that, I contracted with <strong>Webvilág Kft.</strong> in <strong>2004</strong>. It was a <strong>web development company</strong>, where I was in the role of both a <strongclass="keyword" title="web development">web developer</strong> and a <strongclass="keyword" title="Systems administration">systems administrator</strong>. I have mastered <strongclass="keyword">PHP</strong> there, together with <strongclass="keyword">MySQL administration</strong>. I also built a small <strongclass="keyword" title="routers">router</strong>/<strongclass="keyword" title="firewalls">firewall</strong> out of a PC for office needs. Althogh the company has changed its name to Fejlesztők Háza Kft., you may still contact <strong>Péter Bali</strong> on +36 (70) 318-4050.</p>
<p>My next job came in <strong>2006</strong>, when I contracted with <strong>eWorldCom Kft.</strong>, a small <strong>VoIP company</strong>, developing call center software based on <strongclass="keyword">Asterisk</strong>. 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 <strong class="keyword">Gentoo Linux</strong> because of its possible small size, and performance issues. The company since then fusioned with Virtual Call Center Kft. You may reach my ex-bosses there, altough I don’t know any of their new contacts.</p>
<p>The job that followed was with <strong>Lufthansa Systems Hungary</strong> in <strong>2007</strong>, where I became the member of a large team supporting and administering several thousand servers, mostly based on <strong class="keyword">Red Hat Enterprise Linux</strong> and <strongclass="keyword">SUSE Enterprise Linux</strong>. There I mastered cluster technologies (<strongclass="keyword">Heartbeat 2</strong> and <strongclass="keyword">Red Hat Cluster</strong>); <strongclass="keyword">SAN</strong>, <strongclass="keyword noupper">iSCSI</strong> and <strongclass="keyword">NFS</strong> based storages; <strongclass="keyword">Apache httpd</strong> and <strongclass="keyword">Tomcat</strong> web servers; administration of <strongclass="keyword" title="MySQL administration">MySQL</strong> and <strongclass="keyword" title="Oracle 10g Database Administration">Oracle 10g Database</strong>s; <strongclass="keyword">Bacula</strong> based backup; <strongclass="keyword">Windows 2003 Server</strong> and <strongclass="keyword">Windows Server 2008</strong> (both standalone and cluster) with <strongclass="keyword">Active Directory</strong>, <strongclass="keyword">Group Policy</strong>, <strongclass="keyword">Microsoft Exchange Server 2005</strong> and <strongclass="keyword">Microsoft SQL Server 2005</strong>; <strongclass="keyword">Xen Open Source</strong> virtualization; <strongclass="keyword">Citrix XenServer</strong> and <strongclass="keyword" title="Citrix XenApp">XenApp</strong>; <strongclass="keyword">VMware ESXi</strong> and <strongclass="keyword" title="VMware vSphere">vSphere</strong>; <strongclass="keyword">Nagios</strong> monitoring (and <strongclass="keyword">monitoring</strong> in general); and last, but not least, <strongclass="keyword">Linux hardening</strong> (<strongclass="keyword">SELinux</strong>, firewalls of different kinds, fighting <strongclass="keyword">application security</strong> issues). My boss was <strong>László Kiss-Kalló</strong> there, who can be reached on +36 (30) 429-9483.</p>
<p>All this knowledge came in very handy, when I went to <strong>Brokernet Group Zrt.</strong> in <strong>2010</strong>. The IT infrastructure was in a very bad shape there, and our job was to rebuild most of it from scratch. We utilized <strong class="keyword">Debian GNU/Linux</strong> servers (both standalone and <strongclass="keyword">Heartbeat 2</strong> clusters), <strongclass="keyword">Apache httpd</strong> web servers, <strongclass="keyword">Exim</strong>+<strongclass="keyword">Courier IMAP</strong> for mailing, <strongclass="keyword">Bacula</strong> based backup, <strongclass="keyword" title="MySQL administration">MySQL</strong> and <strongclass="keyword" title="PostgreSQL administration">PostgreSQL</strong> database servers, <strong>Oracle Database</strong>s (both <spanclass="keyword"title="Oracle 10g Database Administration">10g</span> and <spanclass="keyword"title="Oracle 11g Database Administration">11g</span>), <strong>Microsoft SQL Server</strong>s (both <spanclass="keyword"title="Microsoft SQL Server 2005">2005</span> and <spanclass="keyword"title="Microsoft SQL Server 2008">2008</span>), <strong class="keyword">Windows 2003 Server</strong> and <strongclass="keyword">Windows Server 2008</strong> (both standalone and clusters), <strongclass="keyword">Active Directory</strong>, <strongclass="keyword">Group Policy</strong>, centralised <strongclass="keyword">ESET NOD32 antivirus</strong>, <strongclass="keyword">Windows cluster</strong> based <strongclass="keyword" title="Microsoft File Server">file server with AD backend</strong>, <strongclass="keyword">WSUS</strong>, <strongclass="keyword">OTRS::ITSM</strong> helpdesk, <strongclass="keyword">Zabbix</strong> based monitoring, virtualization with <strongclass="keyword">Citrix XenServer</strong>, IT security solutions with <strongclass="keyword">SonicWall</strong> appliances, <strongclass="keyword">SELinux</strong>, <strongclass="keyword">Snort</strong> and <strongclass="keyword noupper">iptables</strong>, <strongclass="keyword">Perl</strong> for system administration scripts, and <strongclass="keyword">PHP</strong> and the <strongclass="keyword">Symfony 2</strong> framework for internal web development. Although much has changed in this list since then, it was my best experience so far. You can contact <strong>Attila Balogh</strong> on +36 (30) 924-8179.</p>
<p>Since I left the company in <strong>2013</strong>, I am working as a <strong>freelancer deloper</strong> and a <strong>systems engeneer</strong> for a <strong>startup network monitoring company</strong>. Here we are building a help desk system using open source products like <strong class="keyword">OTRS::ITSM</strong>, <strongclass="keyword">OpenLDAP</strong>, </p>
<p>In my <strong>free time</strong>, I wander in forests, take pictures, and sometimes manipulate them with the <strong class="keyword">GIMP</strong>. Sometimes I write short novels using <strongclass="keyword">LibreOffice</strong>. I am also developing some software in <strongclass="keyword">C</strong>. 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.</p>
<p>Although I don’t plan to change my workplace right now, but when I do so, I look for firms that can develop my skills and give me financial stability through an interesting job.</p>
