My name is Robert Sedlacek.
I am living in Hamburg, Northern Germany,
but was born in Vienna, Austria on April 23rd, 1981.
I am able to write and speak (and read and listen, of course) in English and German. The latter is my native tongue, though I prefer English movies or books.
You can contact me by email via rs@474.at
or by my telephone number +49 (40) 380 23 051.
My postal address is
You can find me in various channels on the IRC network irc.perl.org. For example #catalyst, #dbix-class and #perlde. I'm also present on the mailing lists Catalyst, Catalyst-DE, DBIx-Class and Hamburg.pm.
Perl was and is my language of choice over the last years. Backed by the huge CPAN software library, it allows for fast prototyping and development. Various frameworks like Catalyst (MVC) and DBIx-Class (database abstraction) provide extreme flexibility, while an active and growing community ensures ongoing development and improvement.
I have started with Perl development back in 1999, but went along with the market and specialized in PHP4. In 2003, I finally came back to Perl. I have utilized Perl for the development of e-Commerce Systems, Content Management, Automated Telemetry Environments, System and Configuration Management and various other web application projects.
The Catalyst Web Framework and it's active and growing community allow fast development of high-quality MVC web applications.
DBIx-Class is becoming Perl's one straight solution to object oriented, vendor agnostic database access, easing development and maintenance of your data focused applications.
You can find me in the contributor lists of both projects, as I regard them as the most advanced ones in the Perl world at the moment.
Some of my recent releases are Catalyst-Controller-Constraints and Declare-Constraints-Simple, if you would like to see some sample code.
I developed in PHP for four years in various projects. Most of the projects involved web applications like Content Management Systems, applications for automated work-flows or administrative systems. The projects that did not involve web applications were mostly automated systems like processing and categorizing systems for large amounts of image data.
This is currently my favorite database for deployment. I am experienced in developing with and maintaining PostgreSQL databases for web applications as well as in automated environments.
Of course I am experienced in usage and administration of MySQL databases, having used it for many applications and projects. I encountered MaxDB (the successor of Adabas) in a large-scale transition from MySQL.
I also have some experiences with Oracle databases. It was used in some larger projects, mostly data-heavy phone call statistics. While I wouldn't call myself an administrator for Oracle, I have experiences for front-end development against it.
While not a real RDBMS, I found Sqlite invaluable for prototyping, smaller data storages, or as a storage to use while developing database-agnostic projects.
I have been using and developing on Linux for about 10 years. My preferred distribution is Debian, but I also have administrative experience with RedHat and SUSE.
In the past I have administrated Linux Web servers (Apache and LightTPD), Mail servers like Postfix and Sendmail. I am also experienced with the other "usual suspects" of services: BIND DNS, Samba, NTP, SSH, FTP, RSync, etc. My ability to write administrative Bash scripts has also proven very valuable.
I have worked with Windows from 3.1 to XP and acquired a MCP certificate back in 2000 for Windows 2000 Professional. But I do prefer Debian Linux these days, both as server and client solution.
I have developed interfaces with several AJAX Frameworks and write valid (X)HTML and CSS via a plain-text editor.
Looking back to over a year of work and research in a usability lab I am able to create designs, structures and concepts to make it easier for your users, customers or visitors to fully use your product.
I find both, carrying out projects myself or working together in a team, very easy and comfortable. While I personally prefer to use Subversion for resource repositories, I used CVS for many years and am very secure in it.
Since I abandoned my TV a few years ago I'm reading much more. I prefer English literature over it's German counterpart. It's pretty much the same with movies and series, which I only consume on DVD these days.
A special interest of mine lies in special spiritual systems. For example the enochian or qabalistic ones. I meditate from time to time and prefer to take a walk instead of taking a train or bus if I'm not in a hurry. Although I don't make music myself, I like to listen to a very broad spectrum of songs, including various sub-genres of Metal, Neofolk, Rave, Trance, Grunge, Cross-Over, Industrial, Noise, Punk and Rock.
Regarding my books, I like R.A.Wilson, Terry Pratchett, H.P. Lovecraft, Clive Barker, some of Steven Kings works and various others as well.
