The presentation was minimal, included some code snippets and was super easy to follow. Appears that it was put together all in Markdown, using a very popular open source tool (which I was not aware of): sli.dev. Highly recommend it for folks who make technical presentations.
p.s in the same space, someone also recommended https://revealjs.com/


Cool, thanks for sharing!
I vaguely remember a js based tool that, instead of a series of slides, gave a massive canvas where going to next slide was moving the viewport into a new location on the canvas. Doe that ring a bell to anyone?
I see plenty of people using Excalidraw that way.
