Your Code Is Perfect. Your Product Is Dead.
Most founding engineers treat design as polish—a layer applied after the real engineering is done. But the highest-leverage design decisions aren’t visual. They’re invisible: error handling, data flow, latency, empty states. Every architectural choice is a design choice. The question is whether you’re making it consciously or letting it happen by accident. A product that technically works but emotionally fails isn’t a product—it’s a homework assignment with a deployment pipeline.
