I started web development in 2015 while studying computer science at university. I enjoyed coding and that's why I pursued a freelance career with confidence and passion for web development. In 2019, the rise of Blockchain technologies captured my interest, and with solid web development background, I quickly became a Blockchain Expert in this exciting field. Through experience in developing over 30 diverse web systems, I have honed my skills in React and Solidity, specializing in web and blockchain software developments. From SaaS, Ecommerce, ERP, CRM, Betting Systems, ICOs, STOs, Defi and NFT Marketplaces, I have successfully executed projects of varying scope and complexity. One of my recent accomplishments is the creation of "Bloktok", a Real Estate Investment System that allows customers to purchase shares of real estate as ERC20 tokens through ICO. Bloktok is an online platform serving the Chilean market, offering a seamless investment experience. Thank you for considering me as your web development partner.
