As someone who has been actively searching for such role since August, I believe to an extent I understand how you feel.

My rejection mails is definitely over 120+ at this point. I just have to keep pushing till I see a company that values the skills and culture I bring to the organisation.

That aside looking forward to the continuation of your work. Also there's actually one Nigerian Community Manager for a foreign company I know, Amarachi Azubuike who's doing amazing stuff at Sourcegraph.
