Matt Pocock's skill for deepening modules — restructuring prototype code into something long-lived with cleaner layer dependencies and easier navigation.
Most things I build start as a fast prototype to test a hypothesis. Once a hypothesis is validated, the code needs to graduate into something long-lived — clearer module boundaries, tighter layer dependencies, easier to navigate. This skill is what I reach for at that transition point.
Strong at deepening modules: pulling related logic together, untangling layers, and making code production-ready without a full rewrite.
