sounds like a good time to work on a harder problem :) OP is crushing it on their product. Given the OPs description, we can also infer that the OP works somewhere that commits correlate with output well.
A few interesting questions that come to mind.
1 - Does OP feel like they are doing the same things over and over again?
2 - Does OP want to work with better/more skilled engineers?
3 - Is OP setting the technical direction? Do they want to?
Being the top coder by commits in a group of 350 is a super power, however many "Hard" software problems are resistant to code throughput as a fix. There are extremely difficult software problems that take years to produce the ~1k line solution.
It seems to me, though, that OP vastly much better at that, than the others available. And that his co-workers have noticed this too.
