Day 1–10
</> SofaNerd · Build in Public

I'm building an app.
On the couch.
With AI.

My honest diary — from business woman to developer. With Claude as my co-founder, ChatGPT as my ghostwriter, and tea as my only fuel.

What is SofaNerd?

I'm Katja. Freelancer specializing in project & customer success management. I've spent my whole career in startups — I love turning ideas into reality, the pragmatic way.

By day, I get teams to peak performance. By night, I'm building an app — with zero coding skills, no team, no budget. Just an AI called Claude that sometimes does what I ask and sometimes just does its own thing entirely. My co-founder, basically. And ChatGPT, who sorts my thoughts before I put them into Claude's mouth.

This is where I tell the honest story of how it's going. The breakthroughs. The confusion. The moments when Claude creates three folders I never asked for. And the ones where suddenly everything works — and I have no idea why.

Because “Build in Public” doesn't mean everything works. It means everything is real.

The Team
🤖
Claude
Co-Founder

Writes the code, explains the world to me, occasionally throws in a compliment. Never says “that's not possible.”

💬
ChatGPT
Ghostwriter

Sorts my chaos. Writes the prompts that Claude actually understands. The quiet force behind the scenes.

🍵
Katja
Startup Soul with a Couch and a Vision

By day, she turns ideas into reality. By night, she builds apps — with zero coding skills but energy that just won't quit.
