Complytron HTML sitebuild and Javascript programming

From custom webdesign, I created the website based on HTML and Javascript ES6.

In 2019, an IT company were asked to make a custom-developed system. At first, it was only about sitebuild and the fact that when I am done, the current developer will insert my HTML code into his own system. However, the developer left the project and his code too, which I didn’t understand, but I offered to write everything in plain Javascript (we didn’t want dependencies), because it’s faster than learning to program in Go language. The client agreed with it, and the site was completed in about 1.5 months. Since the page is specially used only on desktop, it is not responsive. There is no database behind it, as I fetch the data from the backend via the Rest API.
