PHP-wise I'm involved in the Smarty Template Eninge, created a PHP CFPropertyList (Apple's .plist, xml and binary), some yet undocumented CommandLine Application Utility.

Javascript-wise I have released URI.js and love jQuery and usually build my stuff around it. I haven't released a great many plugins, as time for documentation etc. is, well, not always there. A context menu handler (capable of polyfilling HTML5), a LocalStorage interface and the POC Browser Event did get published, though.

I've been working on few large and time consuming projects, rather than many small things.

Lakeparty.de has gotten the bulk of my time and resources in the past years. I did the architecture of the software and was involved in the system architecture and customer support. I worked with PHP, HTML, CSS, Javascript and Actionscript. Used MySQL, PostGreSQL, memcache, gearman, sphinx, OpenLDAP, InspIRC and ejabberd.

gallestro.de (the web application) also received quite some attention. I architected and implemented the application - from flexible data handling tools to worklfow guidance, automatic visual analytics. Integrating a whole bunch of foreign systems (MS Office, to name something well known). I worked with PHP, HTML, CSS, Javascript and Java. Used PostGreSQL, mdb, memcache, ActiveDirectory, MS Office (read-write from WebApp), and a whole bunch of (business intelligence) tools you probably won't know anyways.

bodensee.de's front end was implemented by @derSchepp and me.

cruise.ch and schwaebische.de are plattforms I did consulting work for.

ticedo.de, a system somewhat like eventbrite was built by trainees under my supervision.

bonanza-events.de is one of the few actual (small and simple) websites I built.
