I have been building FULLY-RESPONSIVE websites for a long time. I have also been building a website for a company. I am well-efficient in HTML, CSS, BOOTSTRAP, and JS for animations and cool effects for our website. You can also view my work here: https://github.com/snehiljha, my GitHub profile. All of my websites pass the MOBILE-FRIENDLY-TEST, a test that tells about the website's responsiveness of the website i.e it will function on both the web and app.
