XMPP Powered Projects
XMPP (also known as Jabber) is new generation IM system. You may find my works concerning this technology here, on this page.
I've been involved in Jabber community since several years already, mostly on JabberPL forums and Psi client development and forums. I am also a member of XMPP Standards Foundation.
I think my first independent XMPP-related project was (and still is) Suuga - my math bot. Someone could say that it's just a simple calculator, but I really like it :)
I also managed to earn my first real money thanks to XMPP and Google Summer of Code 2006 (no, I didn't participate just for the money, of course...). I created a set of tools implementing XEP-0070, providing XMPP-powered authentication for HTTP (and not only). This project is currently on hold, but I still have some ideas for future improvements.
My most known project is (as I guess) Jobble, co-authored with my friend koniczynek. Yes, yet another Jabber users map ;)
And.. the previous paragraph may not be 100% true now, as I became official Psi developer on 24th January :) Psi is more well know than Jobble, that's sure. But on the other hand, Jobble is more "my" than Psi is ;-)
