    Designed and built the WEPRO web application for allowing members to create profiles and connect to each other. Features include editing background, inviting friends, live streaming, account management etc. Used RESTful APIs to communicate between frontend webpages and backend services which are set in AWS (React, Angular, Vue, Node.js, PHP, Bootstrap, HTML, SCSS, MongoDB, MySQL, Spring Boot, AWS). Link to the website: https://wepro.biz Developed the CBID marketplace for crypto collectibles including EtherDogs, LinglongCats and CobeFriends based on Ethereum. Built interactive APIs talking to ETH Blockchain and designed some smart-contracts of these crypto assets. Provided functions of buying, selling, transferring and searching digital assets. Created the QRCode scanning feature combined with DAPP (React, solidity, ETH Blockchain, web3.js). Link to the website: https://cbid.net Designed and developed a decentralized social platform TwiChat. The platform is based on an independent 3.0 blockchain network and ensures that all data is authenticated, secure, and cannot be tampered with. The feature solves the trust and fraud issues of existing centralized platform, and provides users with a safe, transparent, and efficient next-generation social messaging ecosystem (React, Angular, Vue, Spring Boot, MongoDB, EOS Blockchain, AWS).
