Frank Denis worked for years for OpenDNS, one of the largest recursive DNS services on the Internet. While there he developed DNSCrypt, which has many users and was instrumental in pushing for encrypted DNS. And looking through his github, he has other DNS tools as well. DNS is a contentious issue and I don't agree with anyone on everything they say about the subject, but I agree with Frank here on the waste of absurdly low TTLs and in any case it's wrong to think he is inexperienced.
