conjoon
conjoon is an open source personal information manager developed with Zend Framework and ExtJS. Jesus Garcia considers it as “the epitome of web applications developed with Ext JS” in his book “Ext JS in Action“.
I’m conjoon’s main developer and it’s project leader.
Ext.ux.Livegrid
I introduced Ext.ux.Livegrid in 2007. For the first time, developers had now the functionality to implement grids in ExtJS with hundreds-of-thousands of records without paging, which was a great ui improvement for their clients. It grew out as a sub project of conjoon and is used by mid-sized to Fortune 500 companies.
…ongoing projects
Whether it is the maintenance of extensions contributed to the ExtJS framework or consulting for community projects (here with Thorben Ziemek attending one of Tobias Uhlig workshops), I’m involved in various open source projects. Yet, there are also a few projects unnamed, planned to get public in the next time.
