I could keep pace until about half a year ago. But it meant hands-on typing code for the full work day. Now with claude I can produce similar output in 1-2 hours, most of the time is spent on iterating and having the LLM review the code and fix it by itself and then me testing everything. There is more risk of letting the LLM make judgements and building the wrong thing and me having a smaller chance of discovering holes in the requirements because claude is happy to confidently make the wrong decisions.
