Full Stack Developer specializing in backend systems and blockchain development.
BrazilWhat I'm looking for
I am a Full Stack Developer with a solid backend background and growing specialization in blockchain development. I build secure, scalable systems using microservices, APIs, and cloud infrastructure.
At TOTVS and prior employers I led development and maintenance of microservices for HR software, participated in architecture and security decisions, and mentored colleagues. I have experience designing and implementing APIs, refactoring and documenting code, and improving UX/UI for connected systems.
On blockchain projects I’ve developed logic in Rust for performance and safety, written and tested Solidity smart contracts, and applied token-based patterns for fungible and non-fungible tokens. I focus on smart contract security considerations and testing practices.
I am proactive, organized, and a strong communicator, with hands-on experience across PHP/Laravel, Node.js, TypeScript, Vue, AWS, Docker, SQL databases, Git/GitLab, and Linux. I seek opportunities to combine backend engineering and blockchain innovation.
