I Programmed a Complete Software Project – While Working Out on the Treadmill for 40 Minutes

It was 5 in the morning. Me at the gym. Not to work out – but because I had an idea I didn't want to forget.

So I gave my AI agent a prompt. A detailed prompt. Then I got on the treadmill.

40 minutes later: A complete MVP. Forms, tests, API integrations, unit tests, end-to-end tests. All done.

I didn't do anything. Just worked out.

What Happened

I was at the gym. In the changing room, I gave my AI agent a detailed prompt:

• A platform I wanted to develop
• All requirements
• Technical details
• Test requirements

Then: Treadmill. Sprint training for my ultramarathon in August.

During those 40 minutes, the agent sent me messages via Telegram:

• Progress reports
• Questions that needed clarification
• Confirmations

When I came out of the changing room, the MVP was done.

What the Agent Did

In those 40 minutes, the AI agent programmed the following:

• All forms with validation
• Integration tests for all APIs
• Unit tests
• End-to-end tests
• Setup for secure port in internal network

I didn't touch anything. Just wrote the initial prompt.

That's the Difference

Normally it would go like this:

1. I write specification
2. I program code
3. I write tests
4. I set up deployment
5. I check everything

That's hours. Days. Sometimes weeks.

For this project: 40 minutes. While I worked out.

How It Works

The secret is not a single AI agent. It's orchestration.

I use OpenClaw – a tool that coordinates various AI agents. Each agent has its task:

• One agent for code generation
• One agent for tests
• One agent for deployment
• One agent for communication (who reports to me on Telegram)

They work together. Coordinate. Follow deterministic processes.

What I Learned

The most important thing: You need good processes.

The AI agent can only work as well as you tell it how to work. That means:

• Clear requirements
• Deterministic workflows
• Test frameworks
• Code standards

When these processes are in place, the agent can work autonomously.

What This Means for You

You don't need a software company to use this. You just need:

1. A clear use case
2. Good processes
3. The right tools

What I show in my AI Agent Crash Course is exactly this: How you build these systems. How you define processes. How you orchestrate agents.

Because it's not about having an agent. It's about having a system that works.

The Result

In 40 minutes of training, I completed a project that used to take me a whole day.

That's not magic. That's system. That's process. That's the future of software development.

And you can learn it too.

The question isn't whether you use AI agents. The question is whether you're at the front.

I've made my choice.
