Piranesi, The Martian, Project Hail Mary, Annihilation.
This is a suggestion as well as a request. If you like any of these books, chances are you'll also like any of the others as well. Hypercompetent/scientist first person narrator dropped into an unfamiliar environment with the task to figure things out as they go. Solving problems, forming and testing hypotheses
I seem to have found my catnip when it comes to books, so this is where the request comes in: What books do you recommend that follow this exact pattern?
I also liked Recursion by Blake Crouch…
