I need a full-stack developer who can deliver a web-based panel that lets users manage their USDT holdings and move seamlessly between crypto and INR. The scope, for now, is tightly focused on wallet management: • Deposit & withdrawal flows for USDT to and from the platform, with automatic INR calculation and clear status updates • A clean, filterable transaction history that records every movement in both currencies Everything must run end-to-end—front-end dashboard, back-end services, database, and the integrations that make deposits and withdrawals possible. While our minimum viable product centres on USDT, the architecture should be flexible enough to bolt on BTC, ETH, or XRP later without a rewrite. Security best-practices are non-negotiable. I expect well-structured code, concise documentation, and a staging link for testing before sign-off. If you’ve built similar crypto panels—or have a clear plan to do so—let’s get started.
