I do not know your specific audience which would see this site, are they customers directly, or would you be using this to show work to get hired at a company? These have slightly different focuses. A customer centric site I would think would focus on things you can do which would help the customer. For example, I setup a Wordpress Install, which automatically does X, and the theme matched, etc. These people are unlikely to do a in depth technical review of what exactly your code looks like. A company on the other hand, will tend to pay more attention to it. They could run your HTML through a validator, look through your CSS, and evaluate your JS coding style at minimum. They could also run the site through Pagespeed, or webpage test. They could check not only if all the above is done properly, but that you are leveraging caching, concatenation, and minification. They are much more likely to ask you very specific questions on the above. In general however, I find that just listing your technical skills is 'OK', but writing a brief statement of the skill, and what it allowed you to do, is likely to get you better results.
