    As a highly skilled and experienced blockchain developer, I possess a deep understanding of the technology and am well-versed in the development and implementation of smart contracts. With a Bachelor's degree in Computer Science and 3 years of experience in the field, I have had the opportunity to work on a variety of projects that have allowed me to gain expertise in different areas of blockchain development. One of my technical skills is my ability to develop complex smart contracts that adhere to the Ethereum Improvement Proposals (EIPs). For example, I have developed a smart contract wallet that allows users to securely store and manage their digital assets using Ethereum blockchain. This wallet implements the EIP4337 standard, which ensures interoperability with other applications in the Ethereum ecosystem. In addition, I have designed the wallet with a modular architecture that allows it to adapt and integrate with new and emerging technologies. I am familiar with using cryptographic techniques in smart contract development to enhance security and protect user privacy. In addition, I have experience with writing smart contracts in assembly code, which enables me to optimize contract execution and reduce gas costs. Currently, I am working as a team lead for a smart contract development team at a company in Vietnam, where I am responsible for leading and mentoring other developers, as well as ensuring the successful execution of projects. My experience and leadership skills make me a valuable asset to any organization in the blockchain space. In addition to my smart contract wallet project, I have also worked on other notable projects in the blockchain space. One such project was a decentralized lending platform where I developed a complex Ethereum smart contract that implemented advanced security measures and token standard ERC-20. This project allowed users to lend and borrow cryptocurrencies securely and transparently without the need for intermediaries. Another project that I worked on was a decentralized governance platform where I implemented the proxy pattern in a smart contract. This enabled users to vote on proposals and decisions using a secure and transparent governance system. Furthermore, I have expertise in developing automated market maker (AMM) contracts, which allow users to trade cryptocurrencies in a decentralized and trustless manner. I have also built a decentralized marketplace platform that utilizes smart contracts to enable secure and transparent peer-to-peer trading of goods and services. In addition, I have experience with developing staking protocols and lending protocols that utilize smart contracts to enable users to earn passive income on their cryptocurrencies while also providing liquidity to the ecosystem. Overall, my experience in developing smart contracts for various projects has given me a broad range of technical skills and expertise. I am always eager to take on new challenges and opportunities in the blockchain space and to contribute my knowledge to the development of innovative projects that can make a positive impact on the industry. I am a proactive, results-driven professional with strong problem-solving and communication skills. I am confident that my education, experience, and technical skills have prepared me well for this field, and I am eager to apply my knowledge to new and challenging projects.
