I'm 26 years old with experience working as a SWE at various big tech companies (Apple, Amazon, Google, etc). I'm a well seasoned developer currently working in SV.

I'm starting a project (backend API open to all developers) where I'm going to own EVERYTHING from beginning to end: Requirements gathering, deciding what to build, designing the system, implementation, load testing, launch, monitoring, bugs, etc

I've done all of the above for various medium sized projects (spanning 2-3 months), but this project is quite big (billion+ users, multi-quarter) so it is extremely important that I do everything correctly (at least 85% correct).

What leadership and project management books/articles would you recommend I read? If they're in the context of tech/software even better. I'm already familiar with CI, Scrum, Agile, etc although I haven't used any of this for ~2 years since joining my current employer.

Just to give more context, the current service HAS to be used by any developer in the world that wants to develop X type of thing, there's no other way around it. This already affects 2 billion+ end users.

My project is a new component of this service that will add an extra (very important and big) use case. However, my hopes are that if this new service is very good, we will eventually migrate all the world to this new service. Hence, I want to do an amazing job at it.

Any other advice would be greatly appreciated :)
