Description: APAX is a platform for tokenizing physical precious metals on EVM with a strong compliance focus. The Next.js UI is mostly built, but much of it still runs on mocked data. We need a full stack developer to finish the Node.js and Express backend, connect MongoDB, implement JWT authentication, and wire the frontend to live APIs so login and the dashboard use real data. Web3 and Solidity are out of scope for this phase. Timeline is about four to six weeks. Whitepaper: https://docs.google.com/document/d/17EIeQJWhz4Lt10gEVmWsEiRhKf8u-cfR/edit
