For each new feature, we end up on a whirlwind tour through the codebase: routing here, access control there, rendering in the frontend. Details that belong together are scattered across the entire system. We keep implementing the same patterns over and over again. What if we named them and made them first-class concepts? In this talk, I’ll show how we can capture these patterns and make them concrete: explicit, data-driven definitions that bring everything that belongs together into one place. The result is more uniform code that is easier to build on, and an architecture that becomes tighter over time instead of accumulating ever more technical debt.
