Wallet Migrator
Built a one-click wallet migrator using EIP-7702 to delegate EOAs and move ERC-20, ERC-721, and ERC-1155 assets in one transaction (with scam-token filtering). Designed an account abstraction pipeline that discovers balances, signs EIP-7702, builds a UserOperation, and executes atomically via Pimlico.

Staking Dapp
Developed a decentralized staking application that allows users to lock their tokens in a smart contract. Implemented reward mechanisms to incentivize long-term participation and token holding. Integrated secure contract management and real-time staking status updates. Utilized Solidity and Web3 technologies to ensure transparency and efficiency in the staking process.

Flash Loan
Developed a Solidity-based flash loan smart contract enabling instant, fee-less borrowing and repayment within a single transaction. Implemented logic to support arbitrage, liquidation, and leveraged trading opportunities on decentralized finance (DeFi) platforms. Optimized smart contract for gas efficiency and secure execution on the Ethereum blockchain.

AI NFT Generator
Developed a full-stack blockchain application for generating AI-based images, uploading them to IPFS via NFT.Storage, and minting NFTs on Ethereum. Integrated Stable Diffusion AI model from Hugging Face for image generation based on user input. Utilized React.js, Solidity, and ethers.js to create a seamless user experience for minting and viewing NFTs with metadata stored on IPFS.

Fractional NFTs
Created a Solidity smart contract for fractionalizing NFTs, enabling ERC721 tokens to be divided into fungible ERC20 tokens.Implemented functionality for NFT fractional ownership, sales, and redemption of fractional shares for Ether. Utilized OpenZeppelin libraries for secure token transfers, minting, and ownership management.
