I accidentally found a page on the internet from the person who started the movement (Derek Sivers) explaining that he created a page to say what he is doing at the moment, as many people asked that.
A friend also made a similar page and he tweeted about it and within a few hours several people decided to adopt the practice, so he created a website, nownownow, to showcase people's /now pages. This is mine!
At the moment I'm using it at work to design a new interface to replace the CMS we currently use and this will require a lot of knowledge to implement.
I already use VueJS at work and in personal projects, which suits me very well, but I needed an alternative for some cases and after looking around a bit I ended up deciding on Astro, which is the tool I used to build this page.
Although this page could serve this purpose, I believe that one where I can put my portfolio would be more appropriate.
