In that case, I doubt any backend positions have such a field. At that point it really is up to the developer to just build one for fun.

I personally find optimizations interesting.

I'm actually going to make major optimizations to my site I mentioned in my original post soon. Hopefully it'll be appreciated by my users and not go unnoticed

I know if I were primarily focused on backend I'd have pages for each project to deep dive into them further and to use image assets to better demonstrate my work.
