Not yet personally, I acted as the technical coach/product owner in a “proof of concept” project of the RWTH Aachen where we used a serverless architecture to also make it as lean as possible (see this article for details).
While I haven’t used it personally I really would like to do more with it. I’m convinced that the computing model and the architectures enabled by it won’t disappear but - quite the opposite - will be seen more and more in the future.
