I noticed that loading the main page results in requesting 19 css files and 8 js files. I suggest combining those to provide a better loading experience.
On the front-end optimisation end, that's my "thing" so hit me up if you want to talk about that!
The CV aspect is fairly unique to this sort of site, which is why I think it gets so much attention in these discussions. But as you can see it is a smaller aspect to the site compared to posts, questions, and even profiles.
The CV feature is rooted in this desire I had to host my resume, shown in its original formatting, on a clean, uncluttered page with stats showing me how many views it gets, by whom, and from where. I can share it with a simple link to anyone interested in seeing it and actually know with some certainty if they looked at it.
