Goldsmith
Gold Rate Calculator & Jewellery Booking App
The brief, answered.
Jewellery customers and goldsmiths struggle to get accurate, real-time gold pricing for polish and lab work calculations. Manual lookups are slow, error-prone, and booking is typically handled offline.
Goldsmith provides live gold market rate integration with an automatic pricing calculator for jewellery work, combined with a seamless appointment booking system for goldsmith shops.

How it fits together.
Flutter app with Firebase backend. Cloud Functions fetch and cache live gold rates on a 5-minute interval to avoid API rate limits while keeping prices current. Firestore stores booking records with real-time sync for admin view.
The hard parts.
Live gold rates vary by source and can be delayed or inaccurate. Implemented a multi-source rate aggregation strategy with fallback logic, and clearly displays rate timestamp so users always know how fresh the data is.
