WorkOS
The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
My dad, who was a minister by day and Forth hacker by night, got me into programming when I was a teenager, and Forth and x86 assembly were my first languages. I wrote a small self-hosting Forth compiler for 8086 DOS (https://github.com/benhoyt/third), a tiny 32-bit Forth operating system for the 386 (I guess you'd call it "bare metal" today). Incidentally, my brother used my Third compiler at his work for a few years to write test scripts for embedded systems.
I still love the simplicity of Forth, and the fact that you can get a full Forth system going in a few KB on a new microcontroller. I learned the basics of assemblers, bootstrapped compilers (though not parsers, because Forth doesn't need a "real" parser), recursion, how to implement control structures, various kinds of bytecode (called "threaded code" in the Forth world), linked lists, hash tables, and so on. I also dislike 3rd party dependencies to this day (Forth has a pretty extreme not-invented here culture).
I was really intrigued by Factor when it came out (https://factorcode.org/), as a modern incarnation of Forth, but I never really used it. By that point I had a "real" programming job and was doing absurd things like writing CGI scripts in C, until I discovered Python in the early 2000's. I stuck with Python for many years and really liked it, though more recently I've moved to Go.
I learned a lot by playing with Forth as a teenager, and I'm really grateful for the language. It was an amazing way to start programming.
Oh I love FORTH. Good set of articles here called Moving FORTH by Brad Rodriguez discussing the implementation of FORTH on various legacy ISAs. Worth a read to understand the internals and beauty of the simplicity of it:

And then there's CollapseOS:

In my AVR phase, I build a FORTH interpreter using the jonesforth page.
Nice introduction to threaded interpreters.

I hacked up a simple forth-like system in golang, by following the overview posted in this hackernews comment-chain:

The result is here:

It's not real, but it was a pretty fun experiment regardless.
