INSIDE THE BUILD

See how the thinking
became the thing.

Builds show what shipped. Insights explain what we learned. Inside the Build connects the two — the problem, the decisions, the implementation, and what changed in the real operation.

Codex vs. Claude Code: I Build Production Systems With Both. Here's the Honest Breakdown.

OpenAI's Codex agent and Anthropic's Claude Code are both trying to be your AI coding partner. I've used both to build real production systems. The differences matter more than the benchmarks suggest.

Build Log: We Let AI Pick Our Tech Stack. Here's What Happened.

We didn't plan the architecture for this build. We just started prompting. Then we had to figure out how to fly the plane.
