I’m a senior software engineer with decades of experience building and maintaining production systems. Old Dog New Flex is my place to write down what actually works — especially where AI meets real software engineering. Not demos. Not toy apps. The messy middle where intent, risk, and production reality collide. The products here aren’t prompt packs or magic buttons. They’re frameworks for thinking, designed to help engineers use AI without accidentally rewriting the platform on a Friday afternoon. Everything here exists because I got tired of cleaning up the same mistakes.
