STOP WAITING FOR DEVELOPERS. BUILD IT YOURSELF.

The barrier to entry has fallen. Today you don't need years of practice to create software. You just need the right AI stack and logical thinking. We will teach you how to go from "I have an idea" to "I have an app on my phone" in 48 hours.
Capacity: max 3 people. We work on your idea, not a demo app.

Who will guide you

I am the co-founder of Rejoy – a mental wellness app for sleep (iOS + Android).

I started coding Rejoy myself and wrote the first ~100,000 lines of code before the first truly usable AI development tools appeared.

Today, I use Windsurf, Antigravity, and Cloud Desktop as my 'AI team', and I have two to three mid-senior AI coders to whom I assign modifications, guide architecture, and approve merges.

The backend runs on Firebase, and models like Claude 4.5 Opus and Gemini 3 Pro help me with the code – exactly the stack we will discuss and adapt to your project in the masterclass.

Stack I use: Windsurf, Antigravity, Cloud Desktop, Firebase, Claude 4.5 Opus, Gemini 3 Pro.

What I built this way

Rejoy – sleep and mental wellness app (iOS + Android).

I had the first MVP on my phone in a few days, iterated it into a product used by thousands of people over the following months.

In the masterclass, you get the same roadmap – but for your own idea.

THE STACK

(Tools)

No complex environment setup. I'll show you my 'speed-run' stack that powers Rejoy and internal tools:

  • Windsurf / Antigravity / Cloud Desktop: AI environment where we write and edit code together.
  • Firebase: Backend and database that works instantly and doesn't require a custom server.
  • Claude 4.5 Opus and Gemini 3 Pro: AI models that help with architecture design, code generation, and refactoring.

Code Language

(What we will write)

We won't learn every framework in the world. We'll focus on making you able to read and modify code generated for you by AI.

  • We'll primarily use JavaScript/TypeScript (frontend + simple backend).
  • I'll show you which parts of the code you need to understand and which to leave to AI.
  • You will get basic patterns (templates) that you can copy and adapt for your project.

THE DEPLOYMENT

(Getting it out there)

Code on your computer is useless.

  • I'll show you how to get it on the web or your phone (TestFlight/APK) within hours.
  • Goal: leave with a functional link or build on your phone – a first version you can show to your team or investors, not a finished product like Rejoy.

WHAT WILL YOU HAVE ON YOUR PHONE BY SUNDAY?

FOR OPERATIONS
🧠

THE INTERNAL BRAIN

Tool to clean up chaos

Drowning in PDFs and Excels? We'll build an app where an employee uploads a file, AI reads it, analyzes it, and saves the result to a clear database.

  • Login system
  • AI Document Analysis
  • Admin Dashboard
FOR SALES
⚡

THE LEAD MAGNET

Client acquisition machine

Want to collect leads automatically? We'll build a smart calculator. The client enters data, the app calculates the result and sends a personalized report via email.

  • Interactive Forms
  • Custom Calculation Logic
  • Email Collection
FOR CREATORS
📱

THE POCKET COACH

Your digital product

Selling know-how? We'll build a mobile app (PWA) containing your course. Part of the content free, part locked for VIP clients.

  • Mobile Design (PWA)
  • Audio Player
  • Paywall
⚠️

An agency will charge you for 'Robust Infrastructure' for a million users you don't have yet. They create a bloatware full of features. With AI, you build a 'Lean' product – maybe less robust, but finished in a weekend and for 1/30th of the price. If the market says NO, you didn't lose €17k.
