About

With extensive experience as a Web3 Developer, Blockchain Engineer, and Unity 3D Virtual Reality Developer, I have honed my skills in various aspects of software development. My expertise includes developing and deploying Solidity smart contracts, creating distributed applications (dApps), and implementing blockchain infrastructure. I have successfully completed projects across different countries, working remotely for clients such as M.I.T. Media Labs and BairesDev. As a freelancer, I achieved a satisfaction rate of over 90% by delivering high-quality solutions in both frontend and backend development. In my recent roles, I developed a Virtual Reality Crypto Casino prototype at LIGHTSPEED Tech Development, connecting the VR experience to the Ethereum blockchain. At INVERT Platform, I designed blockchain infrastructure for land sales on the Ethereum chain, linking NFTs to real lands in the Amazon forest. Additionally, I have a strong background in education, having created and taught blockchain technology courses to underprivileged communities in Brazil. My programming skills span multiple languages, including Solidity, C#, Java, Python, and Go, and I am proficient in using various tools and frameworks such as Hardhat, Ethers.js, Truffle, Web3.js, and Unity 3D.

Best back-end engineers I've ever worked with...​

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly. “
