I can vouch for nostr:npub1v22qyndskpawjnsjn8zce53nwldza5ejw67f8y33ntt8qlmpm5rq7ra0z2, he won the hackathon at satsconf last year and was 3rd place this year. (aside from many other projects) He really knows what he's talking about.

Oh, and he hosts the bitdevs meetings in Brasília too. (monthly meeting of bitcoin and bitcoin related devs).
