Yep. I put my comments like that because I know Devs will ask you about these business rules and relationships before they start building.

You might need 2 devs. One who is specialized in the comments part of Wordpress. Maybe if you look at who built any comments plugin or improved it in Wordpress you could contact those devs.

Because they know that part of the code and they specialize in comments and they showed already they can do it.

And the other dev is the Nostr part. They need to understand nost maybe the system of I think they call it BIPS, the proposals of Nostr. Because probably someone needs to suggest adding some entities to nostr or maybe could use all the current features in nostr.

These both deva need to closely work together and integrate their code.

So I do not think you easily find one developer who knows both nostr and wordpress/comments.

Good luck.
