Who am I

Hey everyone! 👋

I'm the solo builder behind Kupkaike. Wanted to share the story and answer any questions.

By day, I'm an industrial project manager. No CS degree. I taught myself to code as a hobby since 2008.

I kept seeing people wanting to sell digital products on Gumroad and Etsy but struggling with two things: finding a profitable niche, and creating something actually worth buying.

So I built Kupkaike — an AI platform that:

1. Scans real market data from Gumroad, Etsy, Shopify & Amazon KDP to find profitable niches (not AI guesses — 30+ live web sources per scan)

2. Generates premium 10,000+ word products with 8 structured chapters, frameworks, worksheets, and bonus materials

3. Creates all marketing assets: cover image, voiceover, sales copy, Pinterest pins

The whole pipeline: type an idea → get a ready-to-sell product in under 10 minutes.

Built with Next.js, Claude by Anthropic, OpenAI, and deployed on DigitalOcean. The entire platform was built using Claude Code — genuinely the most productive dev tool I've ever used.

Would love your feedback — what features would you want to see next?
