As a developer, I frequently wonder about the exact opposite question: where does one learn about companies in need of developers, and about what these companies do and how they do it. For example, if I were a frontend web developer looking for a company that builds their product(s) as a progressive web app using web components, where would I look?

It's easy to find job boards filled with ads from recruiters; but hard to discover companies that you might like to work for.
