I "accidentally" created one of the fastest modern JavaScript frameworks out there: https://signy.dev/

...according to my own benchmarks (yeah, I know how that sounds).

Next, I'm planning to submit it to independent third party benchmarks, hoping to find out whether my results are accurate... or not :)

I've also just finished a CSS framework: https://iriscss.com/

Now I'm working on a new backend programming language that runs on the Erlang BEAM, along with a few web applications built using this tech stack.
