Hey IH! Lovely to be here!
I was founding CEO of CircleCI, which I started and ran from 2011-2015. These days it's the largest CI/CD company, and was recently valued at $1.7B.
Since 2017 I have been building Darklang, which is an attempt to make it 100x easier to write cloud backends. It's an integrated programming language, editor, and PaaS (good deep dive here). It's still got a lot of work needed, but you can try it out today at https://darklang.com.
Some random things that might make for interesting questions: I did a PhD in compilers/static analysis, worked on Firefox, failed hard at a startup, got kicked out of Y Combinator, have opinions (and a podcast) on dev tools, started in the games industry, and just left SF for NYC.
