These are some of the things/projects that I have been working on.
Astara is an [incomplete] attempt at creating a modular, hackable, minimalist web browser.
Bahasa is a natural language toolkit for Node.js and browsers.
Lithium is an object-oriented programming language that I've been sporadically developing. It's heavily influenced by ECMAScript and Python.
Ouroboros is a metacircular ECMAScript interpreter - i.e., it is an ES6 interpreter written in ES6.
Quinoa (kin-wa for those who are not hipsters) is a replacement for the built-in Node.js http/https modules, as well as XMLHttpRequest and the Fetch API, that works on Node.js servers, Service Workers and in client-side web pages.
