I am for a couple years now. I do consulting work [1] around Rust/Embedded Systems/Systems Engineering, usually helping teams that are either kicking off a project (so helping with planning, scoping, and backfilling knowledge gaps), or people who want help building a proof of concept (so: just build it for me asap) for existing companies exploring new ideas or for startups that are working on demos for investors, etc.
I've been active on both the open source and commercial side of embedded Rust since the beginning, so it's been fun to watch it grow both as an ecosystem as well as from a commercial adoption perspective. Doing consulting makes it easier to help do more open source docs + support in the open, and seems to be one of more sustainable ways to do OSS in my opinion, if you can swing it.
