If you're an experienced developer who hasn't seriously used AI coding tools yet, most explanations aimed at "beginners" will frustrate you — they assume you don't know what a function, a Git repo, or an API key is. You don't need that. What you need is a mapping from concepts you already trust (code review, specs, least privilege, sandboxing) to this new category of tool.

Many developers assume that using DateTime.UtcNow is enough to guarantee UTC-safe API requests. But there’s a subtle issue in .NET that can silently corrupt timestamp serialization and cause external APIs to reject perfectly valid requests. This post explores a real-world debugging scenario involving inconsistent UTC serialization, explains why it happens, and shows how to prevent it in your own applications.
