Throughout my career, I have developed a robust skill set that encompasses both frontend development and smart contract engineering. At RUBY Exchange, I spearheaded the creation of the user interface for a decentralized exchange platform built on the Ethergem blockchain. Utilizing ReactJS for the frontend and implementing state management with Redux, I ensured a seamless user experience. Additionally, I leveraged Tailwind CSS and Material-UI for responsive design and performed thorough testing using the Jest framework to enhance reliability. Prior to that, I served as a Lead Smart Contract Developer at MonoX, where I designed a smart contract structure that addressed liquidity inefficiencies. My work included developing smart contracts using Solidity and conducting extensive testing with Hardhat, all while focusing on enhancing security measures to protect user assets. My journey in the blockchain space began at Bidify Org, where I was a Junior Web3 Frontend Developer, contributing to the development of an NFT marketplace across various blockchains. This role allowed me to gain hands-on experience in integrating smart contract APIs with frontend technologies. My technical expertise spans multiple programming languages and frameworks, including JavaScript, TypeScript, Solidity, Rust, Node.js, and Express.js, as well as deep knowledge of NFT and DeFi ecosystems. méně
