It's pronounced Diane. I do data architecture, operations, and backend development. In my spare time I maintain Massive.js, a data mapper for Node.js and PostgreSQL.
One thing to add: OFFSET can still have performance issues at high enough page numbers, since the first n rows still have to be found, sorted, and passed up. There's another technique called keyset or "seek" pagination which performs consistently; it doesn't do well with nulls and you can no longer jump to arbitrary pages, but if you're pulling a list sufficiently long that this is an issue, page numbers are all but meaningless anyway.
