Perhaps in the future, one of us will fall into the team, expanding the team is a very useful thing for the future.
You are right, if the team lacks a specialist in some of the areas of activity, then the expansion of the team is necessary.
I am confident that in the future they will expand the team and take new people for themselves.
In the early stages of development, the project does not need to involve a lot of specialists, in the future, yes, so if you have experience, you can offer your candidacy.
