E-Commerce Automation

Source once, list across every market

There is no shortage of products — the listing is what stalls. Fees differ by country, shipping eats the margin, and detail pages must be rebuilt per language. Yejua automated that entire stretch.

Yejua Mall — cross-border commerce we run ourselves

Built on what we learned selling directly since May 2025: products are sourced daily from Amazon Japan by AI and kept in live sync with Cafe24. Our commerce automation is not theory — it is verified on our own store every day.

Five-stage planning, then rendered HTML

Feed in the product and you get everything from the brief to the finished detail page. A five-stage pipeline covering competitors and customer voice runs first.

  • Product analysis → competitors → VOC → strategy → structure
  • Three-tier templates: block, page, group
  • 26 layout content contracts
  • Claims not in the brief are never written — no false advertising
  • Korean text rendered in HTML/CSS, never AI-generated imagery
  • Available standalone, as an API, or embedded

Look at what's left, not at revenue

Analyses a Naver Smart Store and produces a profit strategy with an execution checklist. The objective function is contribution margin, not top-line revenue. Anything that cannot be calculated is left blank and marked as such.

  • Naver Commerce API integration
  • Store analysis → strategy → checklist → performance tracking
  • Optimisation against contribution margin
  • Margin diagnosis with missing-input flags
  • Goes past diagnosis into execution
  • Usage-based pricing with a managed option
