Crypto Payments System

Collaborated with a team to develop a comprehensive crypto payment system, supporting payments from major blockchains such as Bitcoin, Ethereum, and Polygon, with token support including USDC. I contributed to both frontend and backend development, integrating features that allow merchants to use a POS terminal in physical and online stores. The system also includes automated refunds and monthly settlements, converting cryptocurrency into fiat currencies like USD, providing a seamless solution for merchant transactions and settlements.
