He said he did a lot of data extraction, processing, and exporting. Sort of an ETL process that pulls stuff together from different sources and exports to different formats (I think). For each verse in the Bible there's a ton of different types of data that can be pulled together and provided in a UI - stuff like translator notes, Strong numbers and lexical parsing of source words (i.e. part of speech, tense, voice, person, declension, mood), lexicon for each word, cross-references, ... and that's just at the translation level. Bible software also usually provides multiple translations, pre-built search indexes, commentaries, study notes, theological texts, and collected sermons and books by historical luminaries.
