Honestly, both of them, I feel ready to take on more responsibilities and extend further my impact on the work that is being done by helping other developers do a better job. I did believe that taking a project that "shakes the foundations" of almost every team in the company could have been a good proof of that. I do agree obtaining the skills and experience is extremely hard, especially on Covid times were you see your teammates once every company party ( we are doing hybrid work, you can go to the office when and if you want, I go often, my teammates of the new team never )
