Tackling property data with readable code

on YouTube ↗46m

" summary

Built a property-tax system for Norwegian municipalities using F# on .NET and Event Sourcing, storing ~dozens of domain events per property to reconstruct state and audit every change. Uses pattern matching, small pure functions and a durations library to handle overlapping valuation periods and messy legacy data. Tests favor isolated domain unit tests with minimal mocking and verify snapshot testing for large outputs, and uses Norwegian domain names for clarity; maintainability and onboarding measurably improve.
