<div itemscope itemtype="http://schema.org/Person">
<p>I am <span class="b" itemprop="name">Gergely Polonkai</span>
(sometimes referred to
as <span itemprop="nickname">W00d5t0ck</span>
or <span itemprop="nickname">Polesz</span>), a <span class="b"
itemprop="jobTitle">software developer, systems engineer and
administrator</span>. I was born on <span class="b"
itemprop="birthDate">7 March, 1983</span> in Budapest, Hungary. I
spent my life moving here-and-there in the country, and finally
settled in <span class="b" itemprop="address" itemscope
itemtype="http://schema.org/Address">
<span itemprop="locality">Budapest</span></span>. Although
I have already found my mate for life, I
am <span class="b">single</span> yet (living in a common-law
marriage), being the proud father of a son and a daughter.</p>
<p>You can reach me on <span class="b"
itemprop="email">gergely@polonkai.eu</span>, or by phone
on <span class="b" itemprop="telephone">+36 (30)
7375-706</span>. I fluently speak and
write <span class="b">English</span>
and <span class="b">Hungarian</span>.</p>
<p>I have <span class="b">graduated in 2001</span>
from <span class="i">Táncsics Mihály Szakközépiskola, Szakiskola
és Kollégium</span>, an architecture high school based in
Veszprém, Hungary. There, I learned
about <span class="b">electricity and elevators</span>, while
getting my feet wet in the area of IT systems
engineering. Together with some teachers, we
developed <span class="b keyword" title="network building">the IT
infrastructure of the school, building it from scratch</span>
with <span class="b keyword">Windows XP</span> based clients,
and <span class="b keyword">Debian GNU/Linux</span> servers
with <span class="b keyword">Squid proxy</span>, an <span class="b
keyword">Apache httpd</span> web server, <span class="b
keyword">Exim</span>+<span class="b keyword">Courier IMAP</span>
based internal mailing and a <span class="b keyword">Samba file
server</span>. Meanwhile, I have created the schools
first <span class="b keyword" title="web development">web
page</span> using <span class="b keyword">Perl CGI</span>, and
later its replacement in <span class="b keyword">PHP</span>.
Although I did that as a student, I consider
it my first job. You can contact <span class="b">Imre
Pataki</span> at +36 (20) 970-5830 if you need more
information.</p>
<p>My first contract was made in <span class="b">2002</span>
with <span class="b">GaTeS Group Kft.</span>, a Budapest
based <span class="b">ISP</span> that served Internet connection
to a large warren. I have mastered Linux based <span class="b
keyword" title="firewalls">firewalling and routing</span> there
using <span class="b keyword noupper">iptables</span>,
and <span class="b keyword" title="QoS">tc for QoS</span>. I have
also created a <span class="b">web page</span> for the company
using <span class="b keyword">PHP</span> and <span class="b
keyword" title="MySQL database development">MySQL</span>. The
company went through several merges since then. My only contact
was Ákos Szabó, whose phone number is not reachable any more.</p>
<p>After that, I contracted with <span class="b">Webvilág
Kft.</span> in <span class="b">2004</span>. It was
a <span class="b">web development company</span>, where I was in
the role of both a <span class="b keyword" title="web
development">web developer</span> and a <span class="b keyword"
title="Systems administration">systems administrator</span>. I
have mastered <span class="b keyword">PHP</span> there, together
with <span class="b keyword">MySQL administration</span>. I also
built a small <span class="b keyword"
title="routers">router</span>/<span class="b keyword"
title="firewalls">firewall</span> out of a PC for office
needs. Although the company has changed its name to Fejlesztők
Háza Kft., you may still contact <span class="b">Péter Bali</span>
at +36 (70) 318-4050.</p>
<p>My next job came in <span class="b">2006</span>, when I
contracted with <span class="b">eWorldCom Kft.</span>, a
small <span class="b">VoIP company</span>, developing a call
center software based on <span class="b
keyword">Asterisk</span>. 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 <span class="b keyword">Gentoo
Linux</span> because of its possible small size, and performance
reasons. The company since then merged with Virtual Call Center
Kft. You may reach my ex-bosses (Tamás Jalsovszky and Szabolcs
Tóth) there, altough I dont know any of their new contacts.</p>
<p>The job that followed was with <span class="b">Lufthansa
Systems Hungary</span> in <span class="b">2007</span>, where I
became the member of a large team supporting and administering
several thousand servers, mostly based on <span class="b
keyword">Red Hat Enterprise Linux</span> and <span class="b
keyword">SUSE Linux Enterprise Server</span>. There I mastered
cluster technologies (<span class="b keyword">Heartbeat 2</span>
and <span class="b keyword">Red Hat
Cluster</span>), <span class="b
keyword">SAN</span>, <span class="b keyword noupper">iSCSI</span>
and <span class="b keyword">NFS</span> based
storages, <span class="b keyword">Apache httpd</span>
and <span class="b keyword">Tomcat</span> web servers,
administration of <span class="b keyword" title="MySQL
administration">MySQL</span> and <span class="b keyword"
title="Oracle 10g Database Administration">Oracle 10g
Database</span>s, <span class="b keyword">Bacula</span> based
backup, <span class="b keyword">Windows 2003 Server</span>
and <span class="b keyword">Windows Server 2008</span> (both
standalone and cluster) with <span class="b keyword">Active
Directory</span>, <span class="b keyword">Group
Policy</span>, <span class="b keyword">Microsoft Exchange Server
2005</span> and <span class="b keyword">Microsoft SQL Server
2005</span>, <span class="b keyword">Xen Open Source</span>
virtualization, <span class="b keyword">Citrix XenServer</span>
and <span class="b keyword" title="Citrix
XenApp">XenApp</span>, <span class="b keyword">VMware ESXi</span>
and <span class="b keyword" title="VMware
vSphere">vSphere</span>, <span class="b keyword">Nagios</span>
monitoring (and <span class="b keyword">monitoring</span> in
general), and last, but not least, <span class="b keyword">Linux
hardening</span> (<span class="b keyword">SELinux</span>,
firewalls of different kinds, fighting <span class="b
keyword">application security</span> issues). My boss
was <span class="b">László Kiss-Kalló</span>, who can be reached
on +36 (30) 429-9483.</p>
<p>All this knowledge came in very handy, when I went
to <span class="b">Brokernet Group Zrt.</span>
in <span class="b">2010</span>. The IT infrastructure was in a
very bad shape there, and our job was to rebuild most of it from
scratch. We utilized <span class="b keyword">Debian
GNU/Linux</span> servers (both standalone and <span class="b
keyword">Heartbeat 2</span> clusters), <span class="b
keyword">Apache httpd</span> web servers, <span class="b
keyword">Exim</span>+<span class="b keyword">Courier IMAP</span>
for mailing, <span class="b keyword">Bacula</span> based
backup, <span class="b keyword" title="MySQL
administration">MySQL</span> and <span class="b keyword"
title="PostgreSQL administration">PostgreSQL</span> database
servers, <span class="b">Oracle Database</span>s
(both <span class="keyword" title="Oracle 10g Database
Administration">10g</span> and <span class="keyword" title="Oracle
11g Database
Administration">11g</span>), <span class="b">Microsoft SQL
Server</span>s (both <span class="keyword" title="Microsoft SQL

title="Microsoft SQL Server 2008">2008</span>), <span class="b
keyword">Windows 2003 Server</span> and <span class="b
keyword">Windows Server 2008</span> (both standalone and
clusters), <span class="b keyword">Active
Directory</span>, <span class="b keyword">Group Policy</span>,
centralised <span class="b keyword">ESET NOD32
anti-virus</span>, <span class="b keyword">Windows cluster</span>
based <span class="b keyword" title="Microsoft File Server">file
server with AD backend</span>, <span class="b

XenServer</span>, IT security solutions with <span class="b
keyword">SonicWall</span> appliances, <span class="b
keyword">SELinux</span>, <span class="b keyword">Snort</span>
and <span class="b keyword
noupper">iptables</span>, <span class="b keyword">Perl</span> for
system administration scripts, and <span class="b
keyword">PHP</span> and the <span class="b keyword">Symfony
2</span> framework for internal web development. Although much has
changed in this list since then, it was my best experience so
far. You can contact <span class="b">Attila Balogh</span> on +36
(30) 924-8179.</p>
<p>Since I left the company in <span class="b">2013</span>, I am
working as a <span class="b">freelancer developer</span> and
a <span class="b">systems engineer</span> for
a <span class="b">startup network monitoring company</span>. Here
we are building a help desk system using open source products
like <span class="b keyword">OTRS::ITSM</span>, <span class="b
keyword">OpenLDAP</span>, and <span class="b
keyword">Zabbix</span>.</p>
<p>In my <span class="b">free time</span>, I wander in forests,
take pictures, and sometimes manipulate them with
the <span class="b keyword">GIMP</span>. Sometimes I write short
fantasy or sci-fi novels using <span class="b
keyword">LibreOffice</span>. I am also developing some software
in <span class="b keyword">C</span>, whose source code is managed
with <span class="b keyword">Git</span>. When Im 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 Im
experimenting with Python.</p>
<p>As an employee I am looking for firms where can I use and
develop my skills, while getting financial stability through an
interesting job.</p>
