I am an expert full-stack engineer specialized in blockchain / web3 development, with extensive experience in creating secure and efficient decentralized applications. My strength lies in implementing smart contracts on various blockchain networks, as well as integrating them with web3 technologies to produce flawlessly user-friendly applications. My responsibilities spanned the full development cycle of secure, high-performance applications involving blockchain, ICOs, smart contracts, and SaaS platforms, leveraging frameworks such as Next.js, Node.js, and React. I implemented CI/CD pipelines with Jenkins, ensuring efficient deployment and high availability across our projects.In addition to blockchain, I led initiatives in AI development, focusing on areas including generative AI, large language models, machine learning, and biometric integrations. My role required strategic technical planning, overseeing product scalability, and guiding teams to deliver solutions that meet the highest standards of security, reliability, and performance.In addition, I possess strong coding abilities in multiple languages, including Solidity, JavaScript, and Python. I am also proficient in using a range of frameworks such as React, NextJs, Node.js, and Truffle to build scalable applications. Furthermore, my expertise in handling both relational and non-relational databases allows me to construct robust systems capable of supporting large-scale operations.I have extensive experience using different blockchain development tools, such as Remix, Ganache, IPFS, and Infura, and am familiar with the blockchain implementation architecture (BCIA) and blockchain security principles, enabling me to resolve potential threats or vulnerabilities in the development process.[BACKGROUND]IoT Developer: Raspberry PI, Arduino, Particle, AWS IoT, Machine Learning, Renewable energy: Wind, Solar, Hydro and other alt energy sources,.[2001-2014]Web Development / Programming, SisAdmin (Apache, Linux, Unix, MySQL, PHP, Subversion), Organic SEO (Search Engine Optimization), Online Business Development, Marketing and Market Research[BACKGROUND - 1997-2001]Knowledge in circuitry design and semiconductors, IC´s.embed systems programming, PIC microcontrollers ,System-on-Chip (SoC) firmware, DSP/BIOS e embedded Linux[BACKEND]PHP, MySQL, PostgreSQL, Zend Framework,MVC (Model View Controller), MS-DOS, Assembly, C PIC ProgrammingFamiliarizado com outras tecnologias e linguagens (ASP, JSP, ORACLE, SQL Server, IIs etc.)
