As experienced blockchain developer and smart contract developer, I handled some technical issues with my background knowledge and expertise in the Wake. - Designed the wireframe and outline about how to integrate the blockchain-based revenue system and game ecosystem. - Under seamless consideration of BSC, Ethereum, Polygon and Solana, determined the reasonable blockchain which can support the multi chain, high transaction rate and low fee. - Updating the web pages to grow up the community, in which play a role as NFT marketplace and incentive the customers and the fans by using web3 technology, phaser game engine, nodejs/express and solidity. - Designing the infrastructure of smart contracts that can guarantee the transparent/direct revenue to investors and players by doing research about governance token and utility token, consensus algorithm(POW, POS), TPS, Side Chain, Rollup etc. Skills: Alchemy · Polygon · Smart contr · Truffles · React · web3.js · Ethereum · React.js · Solidity

Built up a web service application which can protect the NFT duplication and content violation like nude, racism and adult etc. (SPARK) This can be used in NFT marketplaces to protect the asset duplication and content violation. This is called SPARK which is implemented in NodeJS, Express/EJS, MongoDB, Stripe and AI image content analysis. This website has landing page, signin/signup page, Stripe-based credit charge page, Asset review page, API key management page etc. I implemented the Spark from the scratch, such as planning, project designing, database infrastructuring and API interface module. Main problem was at the time when I implemented AI-based image process, NFT duplication search engine and payment gateway. I built up the credit charge system by using Stripe, and implemented the authentication. And I also ensured the users to make sure of their assets against duplication and content rarity. # Skills NodeJS, EJS, MongoDB, Express, Stripe Payment Getway, Email Marketing #

Developed a Solana based NFT musical streaming service. (Blackcats) BlackCats is implemented in NextJS, ReactJS and Solana web3 libraries. This website has landing page, signin/signup page, NFT listing page, Auction pages for buying and, selling and minting pages etc. I implemented the blackcats project from the scratch, such as planning, project designing, database infrastructuring and API interface module. Main problem was at the time when I implemented the context provider and hook functions to access the smart contract by using Metaplex Oysterr common libraries. Metaplex standards and libraries are used to access the Solana smart contracts by using javascript apis, Oysterr common is comprehensive and integrated npm package which can support the dapp application. I had to bind the oysterr-common libraries to nextjs-ways provider and hook modules to access free in everywhere. As a result, without the redux-reduce, I can access the web3 interface to mint and list the Solana-based NFT

CryptoGame is a new NFTs-based game project. It allows you to generate passive income. These passive earnings will be correlated to the existing crypto market prices # Role - Creating an agile, scalable, and attractive front page that can make clients attractive - Writing the Smart Contract to mint, buy, and sell the art of NFT in Solidity - Writing the deploy scripts to compile the Smart Contract by Hardhat and deploys the Ropsten test network. - Integrating with Alchemy Web3 and ReactJS frontend to access the metamask wallet and call the smart contract functions. As a result, I can get the user’s address and balance to mint and trade on the Ethereum blockchain. - Uploading both the meta file and image assets on the IPFS to create the meta data. # Skills ReactJS / NextJS / Solidity / Ethereum / HardHat / MetaMask / ROPSTEN / Moralis / Alchemy / Pinata – IPFS / Moralis # Links https://cgame.tech/
