Become an AI engineer

Build a portfolio that proves it: a RAG app that answers from your own documents, an agent that uses tools inside limits you set, and evals that catch a regression first.

Koda's robot presenting a portfolio board with a chat app, a growth chart and a tool-using agent

What you'll ship

  • A RAG app that answers from your own documents, with citations
  • A tool-using agent that asks for approval before risky actions
  • An eval harness that flags a regression before it ships

Tools you'll use

You'll write Python against model APIs such as the Claude API, give agents tools with JSON schemas and MCP, and grade the results with evals. New to code? Start with the JavaScript or Python course.
