Hacker Seeking Problem

Hi all, that's my first post here, so I hope I haven't crossed any lines with it. In short - I am bored at my current job, but it has some benefits - I have enough free time to pursue my own interests, learn new things and so on. Thus, I don't want new job, I want to work on something interesting as a side project, which hopefully can work out as something bigger in the future. If anyone has anything interesting in mind, which requires a partner, please ping me. I am 36 yo, but work as software developer for almost 20 years. Currently I hold a software manager position, which includes hiring and couching people. I can do almost any kind of business software, last few years I work predominantly in web applications (full stack). My minus is the UI/UX part of the applications, i.e. HTML/CSS tweaking and so on. But I have some very good former employees that I can work with, in case it's needed.
