Not a professional farm but for our own food (as vegetarians); Spain first and now Portugal. Land is cheap and plentiful, a lot of stuff grows multiple times per year. Water is an issue which is why we moved to a wet part of Portugal. We grow all our fruit and veg etc and eggs organically. It would not be very hard or expensive to scale it up somewhat; my neighbours all make enough to live with larger plots of land. No idea how to do it on a large scale. Also I am still a software engineer but working less hours these days.
