Ships fast. Owns the stack. Builds tools other devs actually use.
Full-stack engineer building production systems in TypeScript, React, Node.js, Go, and Rust. Built a marketplace from zero and introduced engineering standards that cut production bugs by 60%. Deep in web3 — shipped multi-chain payment systems across Ethereum, Solana, and NEAR, and wrote a subscription billing protocol in Rust on Solana. I don't just use blockchains, I build infrastructure on them.
Ranked Top 1% twice in Brazil's Programming Olympiad (15,000+ participants). Won prizes at hackathons by shipping complete products in hours, not days. Author of Mario Charts, an open-source React library with CLI-driven integration that external developers can actually use.
I use Claude Code, Cursor, and custom MCP integrations as core engineering infrastructure — AI-native workflow, not autocomplete. Ambassador at Borderless Coding, where I mentor developers for international careers and organize hackathons. I ship clean, composable code that other engineers can read, extend, and build on.
