• Decentralized liquid ETH staking protocol built for stakers, node operators, and the Ethereum ecosystem. • Web (Company): https://www.swellnetwork.io. • Web (Product): https://www.app.swellnetwork.io. • Tech-stack: Web (React.js / Typescript + Node.js / GraphQL / Apollo Server + PostgreSQL + Smart Contracts / Solidity / Ethereum). • Planned the smart contracts structure with separate contracts and Escrow contracts for security and audit and developed mainly part in smart contracts using Hardhat environment in Solidity. • Developed the platform to allow users to register their own node operator with their idea and stake and confirm their favorite node operator in the list. • Developed the smart contracts for the swETH token (company token) based on ERC20 and swNFT token(NFT token) based on ERC721 and deployed them into 3 different networks and connected contracts using Infura and Alchemy nodes. • Used Proxy and Storage logic for smart contract security improvement and integrated Openz

• Blockchain NFT Marketplace platform and Data yield farming and staking platform. • Web (Company): https://www.synesis.one. • Web (Product): https://www.kanon.exchange. • Tech-stack: Web (React.js / Typescript + Smart Contracts / Rust / Solana). • Enabled users who staked SNS tokens (company tokens based on SOL) to post questions and answers, and validate others' answers. • Rewarded users with an SNS token if their answer passed validation, and provided all validated answers and questions to the AI company as training data. • Enabled users to upload their collections via NFT minting and airdrop, and purchase other collections via the sales logic of the marketplace. • Developed the smart contract of each platform using Solana Anchor (Rust) with a focus on optimizing code & storage for less gas fee.

• Social digital product marketing platform using NFT and stripe payment integration and social distribution. • Web (Product): https://www.solsapp.com. • Tech-stack: Web (React.js + Firebase + Node.js + IPFS + NFT + Smart Contracts / Rust / Solana). • Designed and developed the infrastructure and well-formed project of data yield farming DApp and NFT marketplace DApp from scratch. • Developed the NFT marketplace logic for digital product marketing using Solana (Rust) and Firebase for backend development using Firestore. • Implemented IPFS private/public logic and RSA algorithm-based encryption for secure digital product management and product link distributing logic via social platforms - Linkedin, Twitter, Youtube, Tiktok and phone sms (twilio.js) / email (email.js). • Enabled users to upload several kinds of products (video, audio, image, doc, license, etc) and sell/buy products using the card (FIAT) via stripe (stripe.js) or coin as they want.

• Liquidity protocol that provides lending, and borrowing functions with liquidity provide using NFT and Oracle. • Web (Product): https://www.roci.fi. • Tech-stack: Web (React.js / Redux-Saga + Web3.js + Smart Contracts / Solidity / Hardhat). • Designed the Roci FI lending platform architecture and smart contract architecture from scratch, focusing on security and optimization. • Recommended using Proxy and Storage logic for smart contract security improvement and integrated Openzepplin to a smart contract for security logic myself.

• Accelerating investor engagement yield farming DApp. • Web (Company): https://www.maxos.studio. • Tech-stack: Web (React.js / Redux-Saga + Web3.js + Smart Contracts / Solidity / Hardhat). • Planned the smart contracts structure with separate contracts and Escrow contracts for security and audit and developed the main part in smart contracts using the Hardhat environment in Solidity. • Developed the smart contracts for company token based on ERC20 and NFT token based on ERC721 and deployed them into 3 different networks and connected the contracts using Infura and Alchemy nodes. • Collaborated with contract developers on smart contract development for the lending platform contract. • Developed an NFT-based User wallet score to generate an off-chain application using Oracle and integrated it into the lending platform.
