01 The Problem

Indian jewellery buyers face quotes where jewellers bury markups inside 8%–25% making charges, varying purity standards (18K vs 22K vs 24K), tola-to-gram conversions, and tiered GST. Consumers had zero neutral, mobile-accessible tools at the jewellery counter to decode quotes or verify fair market rates before paying.

02 The Engineering Approach

Engineered a lightning-fast, mobile-optimized Web Application / PWA with Next.js and Tailwind CSS. Built a live rate signal engine using CoinGecko PAX Gold combined with regional Indian benchmarks. Developed an instant reverse-engineering quote decoder that computes true making charges directly from final quotes, alongside offline-capable device storage and crisp tactile UI feedback.

03 Production Outcome

Live at karat.amayos.com. Instant quote verification across Indian cities. Enables consumers to decode quotes in under 5 seconds, compare against fair benchmark making charges (8%–14%), and negotiate with hard mathematical clarity. Sub-second load on 4G/5G mobile connections.

04 Why It Matters

Because buying gold in India is often a family's biggest milestone purchase, yet pricing, purity formulas, and making charges have stayed completely opaque for decades.
