Building software that lasts requires thinking beyond individual features to understand how components interact and evolve together.
Boundaries Matter
The most critical decisions in system design are about boundaries—where to draw lines between components, how they communicate, and what each is responsible for.
Design for Change
Requirements change. Technologies evolve. Teams grow. Good architecture anticipates change and makes it manageable rather than catastrophic.
Complexity Budget
Every system has a complexity budget. Spend it wisely on solving actual problems, not on premature optimization or over-engineering.
