Philosophy

Code Reviews > Code Writing

The best code is the code you don't write. I'd rather design away complexity than debug it later.

Type Safety Everywhere

TypeScript is not optional. Types as documentation, not mental overhead.

Measure, Don't Guess

No metrics, no improvement. If you can't measure it, don't call it a decision.
