Build my client's production clothing store, synced to their ERP
A solo developer built a women's clothing brand's production WooCommerce store with AI writing most of the code: a custom block theme matched to the client's React prototype, real-time CommerceML sync with their 1C ERP (including patching a stock parser that silently dropped nested per-warehouse counts and cleaning up roughly 1,000 orphaned variations), and zero dollars in platform licenses. Two client revision rounds of about thirty items each cleared in days, and the whole build took weeks instead of months.
How it works
- Put the client's design system into a CLAUDE.md as flat prohibitions (four colors, no raw hex, zero border radius, 8px spacing)
- Build a custom block theme and WooCommerce store from scratch
- Wire real-time ERP sync over CommerceML
- Have the agent verify its own work by clicking the live store through Playwright MCP and comparing against the prototype
- Diff raw ERP XML against the database to find the parser dropping nested stock counts
- Clean up orphaned variations and ship
Why it’s worth knowing
One developer plus an agent shipped a production store whose stock counts actually match the warehouse — at $0 in platform licenses.
