🧑‍💻 About Me

"Code is law — I just make sure it's good law."

I'm a Blockchain & Web3 Developer and Java Backend Engineer currently pursuing my B.Tech at JSS Academy of Technical Education, Noida (Expected 2028). I build decentralized applications, privacy-preserving protocols, and smart contract systems on Ethereum.

  • 🔗 Specializing in Solidity, Hardhat, Ethers.js, and the Ethereum ecosystem
  • ⚡ Actively grinding DSA on LeetCode, Codeforces & CodeChef in Java
  • 🛡️ Passionate about ZK-style cryptography, DeFi security & on-chain privacy
  • 🌱 Currently exploring DEX mechanics, AMMs, and advanced DeFi protocols
  • 🎯 Preparing for GATE CSE alongside competitive programming
  • 🌙 Coding from dawn to dusk — blockchain never sleeps and neither do I

🚀 Featured Projects

🔐 zkKYC Protocol — Decentralized Privacy-Preserving Identity System

Solidity Hardhat Ethers.js React TailwindCSS keccak256

A production-quality decentralized KYC system on Ethereum where raw PII (Name, DOB, National ID) never touches the blockchain — only salted keccak256 hash commitments are stored on-chain.

  • 🏗️ Designed 4 core smart contracts: TrustedIssuer.sol, IdentityRegistry.sol, ClaimVerifier.sol, AccessController.sol with full KYC lifecycle + DAO governance
  • 🪙 Implemented Soulbound Tokens (non-transferable ERC-721) to bind verified identities to wallets
  • 🔒 ZK-style cryptographic claims — prove constraints like Age > 18 without revealing raw data
  • 🔄 3-of-5 social recovery mechanism for compromised wallets
  • ✅ Comprehensive Hardhat/Chai tests covering reentrancy, expired claims & double registration
