Human Logic, AI Syntax... Note on Content: I'm a Systems Engineer, not a native English writer. To ensure my technical ideas are clear and accessible, I use AI tools to polish the grammar and style. The workflow is simple: I provide the logic, the code, and the real-world experience. The AI handles the "English-to-Human" translation layer. If you find a bug, that's on me. If you find a perfectly placed comma, that's probably the AI.
