Full-stack developer | React, Node.js & Ethereum smart contr
New to Contra
ZAKARIA is ready for their next project!
Built a blockchain-based diploma verification system as my final year project š
DiploChain lets institutions issue diplomas that get recorded on the Ethereum blockchain, so anyone (employers, other schools) can instantly verify a diploma is real ā no more fake credentials.
The stack:
ā React.js for the frontend
ā Node.js + Express for the backend
ā PostgreSQL for data
ā Solidity smart contract for the actual verification logic
Three interfaces: one for institutions to issue diplomas, one for students to manage theirs, and one for anyone to verify a diploma by scanning a QR code or entering a hash.
Graded 16/20 by my jury, and now I'm looking to bring the same full-stack + blockchain skills to freelance projects.
