Episode #28: The AI Code Audit: From Prototype to Production

Welcome to Episode 28 of CTRL-ALT-DEV! Today, Sean and Paul strip back the format for a fireside "Deep Dive" into the reality of AI-assisted software development. With tools like Replit, Lovable, and Bolt, founders are building working software faster than ever. But there is a massive hidden gap between a shiny prototype and a production-ready application. Because AI sounds incredibly confident and presents everything as correct, builders often don't realize the risks hiding beneath the surface. I n this episode, we unpack why every piece of "vibe-coded" software needs a comprehensive Code Audit before it goes anywhere near real users. Key Topics & Highlights: The Vibe Coder Dilemma: Vibe coders are often shrewd business owners trying to replace expensive SaaS subscriptions with their own AI-built tools. While they understand their market and price points perfectly, they often lack knowledge of the Software Development Life Cycle (SDLC). The Iceberg Analogy: Users see the visible 20% (beautiful dashboards and UI), but the invisible 80% below the surface holds all the risk. Paul explains the doomsday scenario: an unsupervised AI fixing a bug at 3 AM that inadvertently locks out 100 site workers the next morning. The 11 Pillars of Great Software: Inspired by a pre-AI developer conference, Paul details the foundational pillars of software that AI often ignores. These include security (zero-day vulnerabilities), performance bottlenecks, code maintainability, accessibility, automated testing, and proper database schemas. End-of-Life Compliance: When you roll an app out, it relies on hundreds of thousands of underlying packages and node modules. Paul explains how these frameworks often reach "end of life" for security updates within two years, requiring constant active maintenance. The £3,000/Month AI Trap: The hidden costs of auto-scaling AI apps are huge. Paul shares a story of a client spending £3,000 a month on Replit due to spaghetti code and auto-scaling. They dropped their costs to under £200 a month by exporting the code, moving to Railway for hosting, and using Claude Code. The True Value of AI Builders: Vibe coding is the ultimate prototyping tool. It allows founders to build an MVP, prove market demand, and even secure investment (like one user who successfully deployed a native app to TestFlight with 40-60 users). Once the prototype proves the concept, you hand the blueprint over to a professional dev team to scale safely.
