I know perfectly Html, css and Javascript. I have created a lot of good sites, you can see them in the portfolio, some examples are absent, as I had to sign an NDA. Sites written me completely satisfy you, they quickly loaded, they are suitable for any size of screens and all browsers. If you still doubt my skills, I will be happy to run your test work. I use the popular Javascript library, but if you need to reduce the number of references to files on the server, I'll use Javascript without libraries. i am ready to work 24/7 full time or part time.
