04 / Writing
Essays on React, React Native, architecture, and AI-assisted workflows — written from shipping real products.
AI has made building software dramatically faster. Solving the right problem has not. Implementation is cheaper; product thinking, distribution, and maintenance still decide whether anything actually gets used.
Learn how software engineers can transition into AI engineering, what skills to learn, which projects to build, and how to turn existing engineering experience into an AI career advantage.
If AI can generate code faster than humans can review it, code review cannot stay line-by-line inspection. The scarce resource is judgment: deciding what belongs in the product, encoding taste into tools, and spending human attention where it actually matters.
