Backend engineer with 6+ years building financial systems and protocol infrastructure. I work primarily with TypeScript/Node.js and Rust, and I'm particularly drawn to problems that demand both engineering precision and financial intuition.
Main stack: TypeScript · Node.js · Rust
Also work with: Solidity · Python · C · JavaScript
Infrastructure: RabbitMQ · event-driven architectures · on-chain data indexing · smart contracts
Anticapture — Governance security framework that indexes DAO contracts, extracts on-chain data, and evaluates protocols against security criteria. Helped protect millions of dollars across decentralized organizations.
Notification System — Event-driven notification service built with RabbitMQ, delivering real-time governance alerts to DAO participants. Designed and built from scratch.
AI-Delegates — AI-driven product for automated DAO voting. Led from ideation to release. Won 3 hackathons.
Quan Digital — Algorithmic trading infrastructure for derivatives markets. Built a Rust SDK for real-time Binance Futures integration and deployed automated trading strategies on live capital.
Fluxus — First yield aggregator on the NEAR blockchain. Core smart contract architecture in Rust: vaults and auto-compounders. Won a NEAR hackathon.
🎓 My undergraduate thesis applied convex optimization to cryptocurrency portfolio allocation — where my engineering background meets my interest in financial systems. https://github.com/LeonardoVieira1630/tcc/blob/main/backtestV3.ipynb
