Solene Gold Fintech App Development (Both frontend + backend)
Budget: ₹12,500 – ₹37,500 INR
Project Title
Frontend + Backend Development for Digital Gold Savings & Rewards Fintech App (Solene Gold)
________________________________________
Project Description
We are building Solene Gold, a mobile-first fintech platform that enables users to save and invest daily in digital gold, earn rewards and vouchers, and redeem gold for jewellery (including lab-grown diamonds via our in-house brand).
The product combines features from Jar & Gullak with advanced rewards, gamification, referrals, and jewellery commerce, and is designed to scale to millions of users.
We are looking for experienced frontend and backend developers (or a strong full-stack team) to build the MVP and scalable architecture.
This is a serious fintech build, not a demo app.
