My Pet Projects

It's a full list of my pet projects (which are still alive). If interested in helping any of them, don't hesitate to email. Also, there are a number of projects, which I haven't fully started yet, because I don't have enough time. If you're a Java or Ruby programmer, I'd be interested to discuss a co-founding opportunity for you: I will pay for all project expenses and you will write software. We will be co-founders. Email me.
