It is extremely mentally demanding to do both, even for someone with an overactive brain. I reached a point of severe burnout in 2025 and cut back to part-time work. I'll have to ramp up my hours again soon because, contrary to one of the other comments, I didn't get rich during 1990s/2000s boom.
As for how I did it, I would wake up very early and put in a few hours of writing, then I would put in a full day's work at the office. After my first twelve years or so in the industry, coding was almost second nature and came quite easily. Also, I do much of my writing and programming in my head while I'm walking, running or biking. (I bike to work and back every day.) By the time I sit down to write or code, I already know what I'm going to write, so it's just a matter of getting it through the keyboard.
But yeah, do both for a few years and it really taxes your brain. In both novel writing and programming, you're carrying an entire world in your brain: the plot and characters are one world, the architecture of the software you're working on is another. By 2025, I truly, literally felt like I needed to be shipped off to a madhouse in the countryside. A hundred years ago, people used to call that "the rest cure for a nervous breakdown."
Anyway, cutting back to part-time work has been a huge help. Sanity restored.
One of the things that's neat about the software field in this day and age is that you can see when someone started out 20+ years ago, when things were pretty easy (relatively) and the boom was still on the horizon.
It's pretty common that someone who was born around the right time to the right people in the right location to become a millionaire by writing some php may do something else, but still consider themselves an engineer.
