Junior Full Stack Developer
Computer Science student at CEFET/RJ (expected graduation: June 2026) with hands-on experience in blockchain development, full-stack engineering, and software design. During my internship at IBM, I contributed to building and optimizing systems using Hyperledger Fabric, Angular, and IBM Cloud, focusing on automation, usability, and performance.
Passionate about technology and innovation, I have developed projects involving decentralized applications, tokenization, and smart contracts. Proficient in TypeScript, JavaScript, Solidity, and Rust, I thrive in collaborative environments and enjoy tackling complex challenges to deliver impactful solutions.
Currently I am studying about Solana but I looking for Full-Stack and Web3 (Ethereum) jobs.
