We don't use an ORM. Notion's codebase on the back-end is much more functional than object-oriented, in the sense that we have many more code that looks like `transformTheData(theData, theChangeToMake): ResultingData` than we have classes or methods.

We do lean very heavily on the TypeScript type system and try to make invalid states unrepresentable.

have you tried "data last" FP like `transformTheData(theChangeToMake, theData): ResultingData` instead? I learned this from Ramda.JS, makes it way easier to leverage currying, ex `change = transformTheData(theChangeToMake); change(theData)`
