The Complete Codex Masterclass: Zero to Hero

Become an Agentic Engineer by mastering OpenAI’s Codex agent. From zero experience to advanced workflows!

I built this course around a real SaaS idea – an AI Jobs Directory. With Codex, we go from idea, to first prototype, to even generating a launch video to get our first users.

You’ll see my iterative process with Codex, from how I use Skills sharpen its outputs to using Subagents to speed up my workflows. Follow along with the course project, or extract my Codex workflows for your own wild ideas.

In the course, I’ll show you how to:

• Choose a useful first version of your app so you can start building without planning every feature.
• Give Codex clear instructions, check what it builds, and improve the result.
• Save your project on GitHub so you can track changes and keep working on it.
• Deploy with Vercel so you have a live link to share.
• Use ChatGPT Sites to deploy your site to users.
• Review your app with Codex and agents to find problems you might have missed.
• Schedule regular reviews so you can keep improving the app after launch.
• Turn a recorded workflow into a Codex skill you can use again.
• Use subagents to split a larger job into smaller, focused tasks.
• Make a short launch video that shows people what your app does.

Throughout the course, I’ll drop core Codex concepts, so that you can get a hands on feel for what it takes to build an app from scratch, then maintain that app over time with Codex.

Pre-requisites

No professional programming experience required, all you need is a ChatGPT subscription!
