doodle-monster

Doodle explainers on practical AI engineering, for working developers and builders. Each video takes one idea, explains the theory in doodles, then walks through a practical example you can use in your own app.

What you'll learn: LLM evals, RAG quality, AI agents in production, structured outputs, guardrails, retries and timeouts, observability, and the backend and systems fundamentals underneath them (databases, queues, caching, rate limits, system design).

A new lesson every day: a 10 to 12 minute deep dive at 7 pm IST, plus one-idea Shorts in between. Sources are in every video's description, and written deep dives go up on dev.to, Medium and Substack.

Made by Vishesh Baghel, a software engineer who learns the fundamentals deeply and shares every lesson free. Claims are checked against primary sources; any fix gets a pinned comment and a line at doodle.monster/corrections.

Free forever. Subscribe to learn AI engineering, one doodle at a time.
