|Resume
I am a Blockchain enthusiast inspired by the transformative potential of decentralized systems. With a strong foundation in blockchain technology and hands-on experience working with networks such as Ethereum, Solana, and Sui, I have developed a variety of applications, including fungible tokens, NFTs, DeFi protocols, and lottery contracts. My recent focus includes exploring low-level operations, such as EVM opcodes, blockchain CTF challenges, and gas optimization techniques. Additionally, I am deepening my expertise in Solana and Rust while leveraging the innovative features of Sui. My background as a Web2 full-stack developer equips me to tackle challenges with a structured and user-centered approach, and I am dedicated to staying current with the latest developments in the blockchain ecosystem.
Skills
Lottery (Sui)
The Lottery smart contract on the Sui blockchain allows for the creation of lotteries with ticket fees paid in the native SUI token. Users can purchase tickets to participate in the lottery. The owner is responsible for drawing the winner, after which a portion of the total funds is allocated to the owner as fees, while the remaining amount is awarded to the winner.
Multi-Signature Wallets (Solana)
The Multi-Signature Wallet on Solana is a decentralized application (DApp) designed to create, manage, and execute transactions securely through a multi-signature mechanism. This project is built using Anchor, a framework for Solana programs, and leverages the Solana blockchain's security and speed to ensure efficient transaction management among multiple authorized users.
Quanta
Developed a decentralized DeFi platform for lending and borrowing, allowing users to earn fixed interest on deposits and borrow assets by providing collateral. The platform offers secure, flexible options with dynamic interest rates based on utilization.
OnePiece NFT Marketplace
Developed the ERC-721 NFT collection OnePiece (symbol: OP) for minting, buying, selling, and relisting NFTs, with details stored on IPFS. The smart contract was built in Solidity and deployed on Sepolia. Future plans include adding Royalty NFTs.
Multi-Signature Wallets
Developed a Multi-Signature Wallet Platform, including Multi-Signature and Factory Contracts. Users can create wallets with multiple signers and set approval thresholds. Contracts were tested and deployed on Sepolia.
Crypto Tic Tac Toe
Built a Solidity Tic Tac Toe game with ERC-20 betting (GT). The contract handles all game logic and is deployed on Sepolia. Users receive 5 GT upon sign-up.
Crypto Profit Swap
Created a project to display real-time token prices across DEXs on Solana for profit calculation. Integrated Jupitor, Orca, and Raydium for the proof of concept.
Arbitrage Bot (Uniswap and SushiSwap)
Developed a Node.js script to identify arbitrage opportunities between Uniswap and Sushiswap DEXs. Users input profit percentage and slippage, and the script detects price discrepancies, executing profitable swaps. Future plans include integrating more DEXs and refining the approach to blockchain-based interactions for arbitrage.
Kodefast
Kodefast is a low-code platform for creating and customizing applications with real-time capabilities and automation. It supports dashboards, reports, and multi-tenancy, leveraging AI-powered prompts for development. I contributed significantly using Node.js and Vue.js to enhance user experience.
