I’ve built SP-API tools before. I can complete your Python + PySide6 repricing application by integrating the live Amazon SP-API (Catalog Items and Product Pricing), implementing SQLite caching for UPC↔ASIN and custom overrides, and polishing the UI with progress bars, thumbnails, and keyboard navigation. I’ll ensure all existing batch, throttling, and pricing logic works seamlessly with live data, update Excel/TSV outputs to match your current format, and deliver clean, fully documented code with a 60-day bug-fix warranty. Previous SP-API projects I’ve worked on include [example repo/project] where I built a multi-channel repricing tool and a catalog-sync automation script for Amazon sellers.
