I don't know why you think there's anything resembling "good stories" (I don't even know what would constitute a good story - swash buckling adventures?). It's just grimy-ass runtime/driver/firmware code interfacing with hardware features/flaws.
95% difficult, stressful and surprisingly tedious work
4% panic, despair, insecurities
1% friendly banter with very smart people
If I had to do it all over again, I wouldn't, even though it allowed me to retire early.
But, in summary, it was grinding, grinding, and more grinding, with large dollops of impostor syndrome on top of it.
Met lots of nice smart people, but none were as impressive as the folks at NVidia. I was not worthy of being there.
