I build practical data-quality tools for cross-border e-commerce and procurement teams.
CatalogDelta accepts customer-authorized product snapshot JSON, standardizes Chinese SKU attributes, validates identifiers and price semantics, and detects comparable price or stock changes between two observations.
- No website scraping, login automation, cookies, or account credentials
- Deterministic normalization and exact decimal calculations
- Clear non-comparable states for currency, price-basis, range-price, or missing-price conflicts
- Data-minimized logs and explicit customer authorization
The current release supports one clearly documented candidate JSON adapter and synthetic examples. Compatibility with a customer's real export format is confirmed before operational use.
