Tableware store: 31 parts designed and built on a free theme, plus an email pop-up and a server that creates products from Claude.
More than ten years writing software, and my own stores as the lab. Apps, platforms, websites, SEO and ads: I build it, test it on my own business and turn it into products you can use.
What I build for myself and already works, packaged so you can use it without depending on anyone.

A premium-looking Shopify store on a free theme. Describe what you want in the Claude app and it is built into your theme, no code, live store untouched.

Hi, I'm Chema.
I'm from Seville and live in Almería, with my daughter and another one on the way. I've been building things on the internet since I was 14.
For more than ten years I've built apps, platforms and websites for all kinds of clients, and I run my own stores, where I test everything before I offer it.
What I enjoy most is solving someone's real problem. With AI I do it far faster and better, and Kafkine is where it all comes together.

I build what you need, from the app to the campaign. Before we start you know what it costs, how long it takes and what it should achieve, and you pay in monthly instalments.
