We launched the ECflow blog. Here we'll share what we learn building cross-border e-commerce (Shopify), KDP publishing, and AI tools — the wins, the failures, and the real numbers.
Why we're writing
Everything we've built so far started from a real problem we hit ourselves — the AI interview practice tool, Shorui-tsu (document AI), JP2CN, the Shopify startup guide, and the KDP publishing toolkit.
Until now, the lessons lived only inside the products. We're writing them down so anyone facing the same problems has a clear path forward.
Three topics we'll cover
- Cross-border e-commerce & Shopify: first-store setup, product page craft, and the traffic experiments that didn't work
- KDP publishing: lessons from 46 published books, cover design, and real keyword research
- AI tool development: solo building with Claude Code, prompt design, and shipping to launch
The numbers, in the open
What indie makers want most is the raw truth: how much does it actually sell? We'll publish the numbers and the failures, not just the highlight reel.
The goal is a blog you can read and go build from — reproducible first-hand knowledge, not recycled templates.
What's next
First up: the full picture of launching a Shopify cross-border store, from domain to product listing.
