SaaS Platform for Digitally Verified Jewellery and premium brands

I’m looking to build a SaaS platform for jewellery and premium brands that gives every physical product a Digital Product Passport.

A brand can register each jewellery piece/product on the platform and attach a unique QR code or NFC tag. When a customer scans it, they see a verified digital passport containing product details, authenticity/certificate information, warranty, and ownership history.

The platform should also allow ownership transfers, so when a customer resells the jewellery, the digital ownership record can be transferred to the new buyer.

Blockchain will be used as a tamper-evident verification layer for product registration, certificates, timestamps and ownership-transfer records, while sensitive customer/product data remains off-chain.

MVP requirements

* Brand/admin dashboard
* Product creation and bulk upload
* Unique product ID generation
* QR code generation
* NFC integration
* Customer digital passport page
* Product authenticity verification
* Ownership claiming and transfer
* Certificate/warranty management
* Product/ownership history
* Blockchain integration
* API for future Shopify/e-commerce integration
* Basic analytics for brands

I want the system to be scalable so that we can initially target jewellery brands and later expand into watches, luxury fashion, sneakers, collectibles and other high-value products.

I’m looking for someone who can handle the full-stack development + blockchain integration and help choose the appropriate technical architecture.
