Shaping the build

Software engineering has never been just about implementing a spec. Researching the problem, asking questions, challenging assumptions, making technical and product decisions, working with users, and adjusting the direction based on feedback have always been an important part of how I work.

What feels different with AI is the speed. We can move much faster from an idea to a prototype, get feedback, learn, and iterate again. And that makes the ability to “shape the build” even more important.

I especially like the focus on ownership and measuring success by the value we create, not just the tasks we complete.

Great read — and I think especially useful for engineers early in their careers.
