Sobre mim
I am a senior full-stack and blockchain developer with 10+ years of experience building secure, scalable, and high-performance web platforms. I specialize in Golang, Node.js, React, smart contracts, and blockchain infrastructure.
I have built payment gateways, DeFi platforms, cross-chain bridges, NFT systems, and custom backend architectures. I work directly with self-hosted nodes, on-chain indexing, and security-first designs.
I don’t use copy-paste code. I build clean, auditable, production-grade systems that scale and stay secure.
