Very, very impressive. I just spent the last hour going down the rabbit hole of reading your blog and browsing through your different side projects (which I can only recommend to fellow HN readers, the programming language posted here really is just the tip of the iceberg). Creating your own programming language is remarkable in its own right, but then using it to build your own frontend & backend frameworks, search engine, productivity suite, 3D renderer and a bunch of other apps ist just impressive on another level.

What I find most fascinating about your side projects is how you bring together a number of different skills in a way that looks almost effortless. Knocking out a search engine or a twitter reader as a throwaway learning project is one thing, but doing it over the course of little more than a week with a well designed UI in a way that ends up being useful in your own workflows? That not only takes some serious work but also the ability to correctly judge which directions not to go in, which can be one of the hardest aspects of developing software.
