I can't code. I'm building a product with Claude anyway.
Hi, I'm Nghia. I live in Vietnam and I work as an engineer, the kind that doesn't write software.
For 21 days I'm going to build a small digital product with Claude and try to sell it. Picking the idea, making the thing, the checkout page, all of it. One hour a day, around my day job.
I don't write any of the code. I vibe code it*, which is a long way of saying I describe what I want and Claude does the typing.
Everything goes on this site while it happens. What I made, what broke, and the numbers. The bad ones too.
Status: the challenge ran from September 23 to October 13. The final report is in Final report.
New here? Start with the first guide. I wrote it before day 1, and it's the tool I'll use to pick what to build.
* Vibe coding. I describe what I want in plain words and Claude writes the code. I type in Vietnamese, my first language, and what comes out is normal English. It's fast, and it means you don't have to be a programmer to build something. You have to be someone who can say clearly what they want.
