I've had lots of practice while participating in this project. First of all, getting most of the development responsibility is quite a mobilizing event. You know if you don't do it - nobody does it for you. And you can't change your mind, since it's not you, who depends on this, but dozens if not hundreds of people around the world.

I've managed to work with something that goes beyond one server. I could even say, that was an important experience of looking at the project as an architect, rather than as a developer responsible for a particular part of an application.
Another benefit that I got from this experience - breaking every limitation in terms of programming languages and technologies. Avalanche infrastructure was full of things I didn't know. And with that I've lost any doubts that I can learn anything, should I try.
