1. What problem are you optimizing for? "The job" encompasses code, but it also encompasses staffing. It's a lot easier to hire Java developers than Scala developers. In a leadership role, your responsibility isn't just the day-to-day code - it's the whole project. 2. Microservices vs monoliths is a see-saw. You build a monolith, find it's a brittle, incomprehensible hairball, and you break out microservices. You build microservices, find that operational headaches are killing you, and start consolidating them into monoliths. Which kneecap do you want the bullet in? 3. Fix what breaks. 4. Continuous integration is vital. But it needs to be evolved along with the system. There's this thing I say... "Have computers do what computers do well, have humans do what humans do well". Handling complex and repeatable behavior (i.e. builds and test suites) should absolutely be automated as much as possible. Think continuous integration sucks? Try handing it off to humans for a while! You'll learn whole new levels of pain. 5. All process is about (or should be about) specific, discrete communications issues.
