Don’t be too hard on yourself, the learning curve as a new infra/platform engineer is VERTICAL.
Try not to hide that you’d benefit from some bootstrap assistance in a misguided effort to “not look clueless”, that’s a fast ride to a bad perf review or worse.
One strategy that is incredibly effective in this situation is to ask if you can shadow an experienced/skilled team member for a sprint or two, and then switch to pairing with the same type of person for the following month or two.
Your rate of learning will skyrocket using this approach, compared to trying to “go it alone”
Good luck and enjoy the ride!
