I agree with the principle of wanting to see code but keep in mind that expecting Github (or similar) is a bit ageist. I definitely went through a phase of my life where I coded like crazy and produced lots of interesting side projects, but that was long before Github or even Sourceforge existed. So I could point you towards some interesting stuff I passed around the BBS world in 1985, except that even I didn't bother to keep a copy after its usefulness faded.

I still have a bit to show on Github and mean to put up more when I have a chance but still, most developers find that when you've got a decade or more of experience, you start to want to take on new challenges and experiences (whether family or woodworking) in your free time rather than more programming.
