Who is the deputy at Hogwarts School of Witchcraft and Wizardry after end Harry Potter Deathly Hallows?

There's a bit of a tricky answer to this, as the books never explicitly state who the deputy headmaster is after the events of Deathly Hallows. However, we can make some educated guesses based on the information we have:

* Possible Candidates:

* Minerva McGonagall: While she is the headmistress in the epilogue, it's highly unlikely she'd continue to hold both roles. She likely would have appointed a deputy to handle the daily administrative tasks.

* Pomona Sprout: She is a senior professor and the head of Hufflepuff, making her a logical choice.

* Filius Flitwick: As the head of Ravenclaw and also a senior professor, he could have been considered.

* Severus Snape: While he died during the Battle of Hogwarts, it's possible he had a successor in place before his death.

* The Likely Answer: It's most likely that Minerva McGonagall appointed a deputy headmaster to help her manage Hogwarts. However, the books don't provide us with a specific name.

Note: There's a strong possibility that Rowling might have mentioned this in interviews or other supplementary materials, but the books themselves don't explicitly answer this question.
