The Hidden Value of Type Safety in Large Projects
When your app grows, types become your allies

I didn't always value type systems. Early on, it felt like a hassle — too verbose, too rigid. But as projects grew, so did the number of bugs caused by assumptions. Types became not just helpful, but essential.
In a complex backend, strong typing:
- Documents the data structure
- Prevents accidental misuse
- Makes refactoring safer
If you're using TypeScript or Kotlin, you know this already. But it's still tempting to cut corners in the name of speed.
Type safety is like writing with a spell checker. It might slow you down slightly — but it catches things you'd otherwise miss.
