Disjoint thoughts on AI and the future of building things. | Cory Zue

Personal blog of Seyhan Dzhamur

The one skill that separates senior engineers from everyone else isn't technical. It's the ability to take ambiguous problems and make them concrete.Retry

We reward complexity and ignore simplicity. In interviews, design reviews, and promotions. Here's how to fix it.

Software development is dead. The marginal cost of code is collapsing. That single fact changes everything that follows.

Writing code is easier than ever. Being a software engineer is harder than ever. The paradox nobody talks about, and what engineers and leaders should do.

Coding agents have replaced every framework I used

A short pep talk I delivered to kick off a Three-Day Startup challenge event. And overwhelming confirmation that the lesson is correct.

Beginners tend to prioritize the wrong things when learning to code. This is my advice for what to focus on.

The barrier to entry for building software has collapsed. The barrier to building something that matters hasn’t moved an inch.

When code gets cheap operational excellence wins. Anyone can build a greenfield demo, but it takes engineering to run a service.
