Coding Agents in Production
Ng's advice helps developers avoid costly production mistakes when using AI coding tools in real-world applications.
Andrew Ng highlights common pitfalls when deploying applications built with coding agents. Developers often skip evaluating trade-offs like latency and compute costs. Ng emphasizes the need for software engineering fundamentals to guide AI agents in making structural decisions. The key capabilities requiring human guidance include full-stack development, data lifecycle management, system architecture design, security, and production operations.
Everyone has done it: You build a new application with coding agents and love the toy version so much that you wind up deploying it without first evaluating trade-offs like latency, uptime, and compute costs. And we all know vibe coders who do this every day and only discover the production consequences later. When a developer lacks the proper grounding in software engineering fundamentals, they can’t steer an agent to make the structural decisions needed for building great applications. In this week's letter, Andrew Ng outlines why understanding the full software development stack, from data management to user interfaces, remains essential for AI engineering. Here’s Andrew’s list of the key technical capabilities requiring a knowledgeable human’s guidance: 🏗️ Full-Stack Development: Planning out API design, session management, caching strategies, and asynchronous processing. 🗄️ Data Lifecycle Management: Picking data models and storage infrastructure to maintain consistency and clean feeds for downstream AI systems. 📐 System Architecture Design: Choosing everything from the monolith versus microservice dilemma to load balancing. 🔒 Security and Reliability: Building in smart failure-handling policies to ensure graceful degradation, unit and integration testing, and security and testing — early and often. 🚀 Production Operations: Configuring CI/CD pipelines, managing databases, and creating observability tools for understanding workloads.
