Build AI Agents From Scratch

54 lessons·9 modules

Made by

Shyam Saktawat

I work on OA Helper and Open AlphaEvolve, and I majored in ML. Interviews keep asking about AI agents, but most of us in college have never actually made one. This course fills that gap. You make one, step by step.
If you know basic Python, you are ready.

How to use this

One lesson a day, in order.

Do not jump to LangGraph or CrewAI on day one. Start at Module 1 and write the loop yourself. In each lesson, run the code, break something on purpose, and see what happens. Then try the interview questions and the quiz. That is it.
About an hour a day. You will finish in about two months.
