Bio (first posted on Lucene Mailing list)
I am 31 years old, born in southern Germany (Bamberg). I studied physics at University Erlangen-Nürnberg and graduated in 2004. Since 1996 I was working in parallel for PANGAEA (Publishing Network for Geological and Environmental Data, http://www.pangaea.de/, it is a library for data publications) as software designer. In 1996 I was one of the early persons started to program Java applets with JDK 1.0.2 (one of them is still available on the PANGAEA homepage, ART) and since then I used Java as my primary programming language.

Since end of 2004, I am working full-time for PANGAEA, employed at the Center for Marine Environmental Sciences belonging to the University of Bremen, where I live now (and trying to get a PhD in parallel). My primary business is now design and development of the fundamental middleware components for PANGAEA. In 2004 we started to use full-text search engines for metadata search. We noticed early, that geographical information systems can take advantage of full text engines, but that search using geographical constraints is also important. Our first FTS was embedded into our backend database (SYBASE), so it was possible to do joins between the FTS and relational tables. Looking for a better solution, I came to Lucene. In 2005-2006 I started a new Open Source Project called panFMP (PANGAEA Framework for Metadata Portals, http://www.panfmp.org/), that uses Lucene for full text indexing and enriched Lucene with the TrieRangeQuery. panFMP is a little bit like Solr, but at the time when the project started, Solr was not well-known to the community. PanFMP uses a little bit different metadata approach and uses the harvesting approach (OAI-PMH), but is comparable.

Since 2003 I am also working in the PHP (http://www.php.net/) development crew, maintaining the web server plug-in for Sun Java System Web Servers (my favourite web server). I also have a small one-man software-company called "Schindlers Software" (http://www.schindlers-software.de). My (IT) interests are Lucene, XML techniques, Data Warehousing, Sensor Networks, metadata dissemination using global standards, global unique identifiers like DOIs,...
