Frontend Engineer
About Me
I am a Frontend Engineer with 5+ years of experience in software development and more than 2 years working with Web3 and Blockchain applications. I focus on building scalable, data-driven decentralized solutions that connect technology and finance in a practical and user-friendly way.
My experience includes working with React.js, Next.js, Node.js, TypeScript, GraphQL, Firebase, and modern frontend tooling. I have built responsive interfaces, dashboards, and reusable UI systems with an emphasis on performance, accessibility, and code quality.
I have also worked extensively in Web3 and DeFi environments, integrating smart contracts and blockchain features using tools such as web3.js, ethers.js, wagmi, and viem. I enjoy solving complex product challenges in decentralized ecosystems and helping create secure, intuitive user experiences.
In my recent role at Spectre AI, I worked on an AI-powered analytics and prediction platform for the cryptocurrency market, collaborating with international teams in English. I contributed to on-chain data workflows, market sentiment analysis interfaces, and scalable blockchain-connected frontend features.
Previously, I developed decentralized applications at Investy Club and high-performance digital products at Red Ventures. Across these roles, I strengthened my skills in component architecture, testing, CI pipelines, and maintainable frontend development practices.
I am based in São Paulo, Brazil, and I speak English and Brazilian Portuguese. I also hold formal education in Web Development, Logistics and Supply Chain Management, and a postgraduate degree in Tech Management in progress, along with a certificate in Decentralized Finance from Duke University.
