I've been doing software engineering for 20 years and approximately half of my total work output has been in the last 2 years. Once you get it set up and maintain it regularly it's easily three to ten times faster
There is no way on earth that you've done more in two years than in 18 years before that. It's not even a remotely believable claim.
I'm just going by github, which has captured the majority of my work since 2007, and says my prior peak was in the ~800 contributions per year, and this year so far I've done 5k+. Not always comparable but close enough I feel comfortable saying "at least 3x"
