Goldsource — sales up 102% in year one
Live metal pricing with guardrails.
Prices update from live markets, but bad data is stopped before it reaches Shopify. A minute-level workflow acquires locks, respects market hours, fetches rates, detects spikes, syncs Shopify, and refreshes the cache — with lockdown instead of risky storefront updates when something looks wrong.
High-performance chart for historical metal prices.
Sell-your-coin intake in Sanity.
Customers register that they want to sell a coin on the storefront, then Goldsource handles the sales process in Sanity — from inquiry to offer and fulfillment.
Safe Shopify webhook processing.
Webhooks are accepted fast, then processed with retries, dedupe, and poison-message handling. Routes verify HMAC and schema, enqueue work with idempotency keys, and use Redis locks so overlapping serverless runs cannot corrupt CMS state.
