A Philosophy of Software Design

Master the art of creating deep modules to reduce complexity and prioritize long-term strategic growth over quick tactical fixes. Build software that is easy to maintain and understand. * **Design deep modules** with simple interfaces and hidden complexity * **Adopt strategic programming** to prioritize long-term system health * **Reduce cognitive load** by minimizing unnecessary dependencies * **Define clear abstractions** that solve problems without exposing internals
