EpicMint

Designed scalable backend REST APIs, MongoDB data models, and Solidity smart contracts (ERC-721) on Ethereum with IPFS metadata storage and automated wallet royalty distribution.

✦Designed scalable backend APIs, authentication workflows, MongoDB data models, and integrated Solidity smart contracts.
✦Engineered automated, transparent royalty distribution directly into Ethereum smart contracts.
✦Architected hybrid backend using Node.js, Express, MongoDB, Solidity, Hardhat, and IPFS/Pinata.
✦Built as the flagship entry for GenIgnite 24-Hour Hackathon at IPEC Ghaziabad.
