What You'll Build

Real tools. Not toy projects.

You'll finish with something you can show off, share, and put on your portfolio.

During the Course

A Coffee Taste Profile Quiz

Build a fully working web app for NovaBrew, a fictional D2C coffee startup. Customers take a taste quiz and get personalized blend recommendations — complete with shareable results. Then deploy it to a live URL anyone can visit.

🚀
After the Course

Your Own Tools & MVPs

Internal dashboards, customer-facing calculators, landing pages with interactive features, automated workflows — whatever your business needs. Deploy it live and share the link. Portfolio-ready.

Who This Is For

Built for business people, not developers.

If you've ever said "I just need an engineer to build this quick thing" — this course is for you.

FAQ

Common questions.

Do I need to know how to code?

No. Zero coding required. The entire course is designed for people who have never written a line of code. You'll direct AI using plain English — the same way you'd brief a contractor or manage a team.

What exactly is Codex?

Codex is an AI coding agent made by OpenAI. It's a free desktop app for Mac and Windows where you open a project folder and have a conversation. You describe what you want in plain English, and Codex builds it. No coding required. It works with a free ChatGPT account — no paid subscription or API keys needed.

How long does the course take?

About 4–5 hours total, split across four modules. Go at your own pace — do it in one sitting or spread it across a week.

What do I get at the end?

A working web app deployed to a live URL (on GitHub Pages, free) that you can text to anyone. Plus a GitHub portfolio and a case study. Not a certificate — actual proof you can build things.

Can I use this for my own projects?

That's literally Module 3. The capstone is designed for you to build your own idea — whether it's a startup MVP, an internal tool, or a side project.
