Younghee Song is a software engineer and AI educator publishing course material on building AI agents from scratch.
His CourseFlix listing carries Build an AI Agent (From Scratch) — a practical walkthrough of constructing an LLM-powered agent without depending on a heavy framework, covering the planning, tool-use, and execution loops underneath modern agentic systems.
Material is paid and aimed at engineers picking up AI-agent construction as a hands-on engineering skill rather than reading high-level descriptions of the field. For a broader AI Agents track on CourseFlix, see the AI Agents category page.
