About us

Sigsiu.NET was founded in 2003.

Beside building web sites we started with developing an emergency disk using FreeDOS and our own live CD operating system Siggix based on Knoppix.

Until 2005 we additionally carried on a repair service for HP notebooks before we attended ourselves mainly to the development of components for Joomla!. Already in 2004 we had the first contact with the CMS Mambo and built our own company site with Mambo.

The Sobi project started in 2006 when we wanted to create a directory website with Joomla! for our own city, but couldn't find a suitable directory component. Since Joomla! is open source, we initially developed Sobi from an existing component. To support the Joomla! open source community, we provided Sobi to all Joomla! users in the Joomla! Extensions Directory (JED). Sobi found a strong response from users, and a large number of feature requests arised. However, the structure of Sobi(1) was not suited to implement these new features, so we decided to develop an entirely new component.

The first Sobi2 version was published in September 2006, 4 months after Sobi(1), and was even more popular. Using an integrated interface for extensions, the functionality of Sobi2 could be extended without changing the core code, which has led to over 80 extensions available on JED for Sobi2. The Sobi2 component has been downloaded over 500,000 times to date.

Four years and many feature requests later, Sobi2 has reached its limits. New programming techniques and Joomla! versions made the development of a new component seem like the next logical step.
The result is SobiPro, which was first released to the public in September 2010.
Since 2011 we have a Membership Club to provide even more support and additional features to the users of SobiPro.

Sigrid Suski

Sigrid lives in a small village near Frankfurt on the Main in Germany.
She studied electrotechnics before she started to work as a software engineer for industrial products using Microsoft C++/MFC.
Since 2009, Sigrid works full time for the Sobi projects.
Her programming experiences started with the programming languages Pascal and C, followed by C++ which is a good basis for developing software for Joomla!, especially since the well known to her object oriented developing techniques find their way into PHP.

Besides her development work for the Sobi project, she is mainly responsible for design solutions, support, quality management and for all business affairs and public relations. Sigrid is also in charge of the translations and documentations for SobiPro and of the Sigsiu.NET websites.

Sigrid is member of the German J and Beyond e.V., of the Joomla! Events Team, and of the Joomla! Social Media team. She is attending JoomlaDay events throughout Europe and beyond.

Sigrid enjoys cuisine and the outdoors in her leisure time, including spending time working in the garden. She also enjoys taking photos, although she doesn't have as much time for photography lately.

Radek Suski

Born in Poland, Radek has been living in Germany for the past ten years.
Since 2006 Radek is providing high quality extensions for Joomla!. He continues his educational studies of Science of Informatics at Hochschule Darmstadt University of Applied Sciences and works full time for the Sobi projects.

As the development leader, Radek is the mastermind for developing SobiPro and the additional applications. As the system administrator he is also responsible for the setup and maintenance of all servers, the forum as well as the demo sites.

Radek is former First Chairman of the PCJ Open Source Foundation Council, member of the German J and Beyond e.V. and OSM Board Member. His other Joomla involvement includes contributing to the work of the Bug Squad, and he is member of the Joomla! Social Media team and a co-leader of the Joomla! Events Team. Radek is a frequent speaker at JoomlaDay events throughout Europe and beyond.

Some people are seeing Radek as a guru, geek or even a nerd. None of this is true of course. He sees himself as a kind of digital vampire. However, instead of blood he needs coffee to live and work. But the sunshine on the monitor is definitely very dangerous because it interrupts the virtual live and doesn't allow to work.
