Lucas de Almeida

Computer Engineering student focused on Blockchain & DeFi security.

I’m Lucas de Almeida, a Computer Engineering student and developer focused on Blockchain, DeFi, and financial applications.

My background combines Computer Engineering with Economics, business, and finance. After working closely with real businesses and financial decisions, I became increasingly interested in the systems behind them and started moving deeper into software and blockchain.

Today, I build and explore Web3 applications across Solana, Ethereum, and Stellar, working mainly with Rust, Solidity, and TypeScript. My interests are centered around DeFi, protocol engineering, asset tokenization, and smart-contract security.

Currently, I’m pursuing my degree in Computer Engineering at UFRPE, strengthening my foundations in programming, computer systems, mathematics, and software engineering while continuing to explore blockchain and decentralized systems through projects and hands-on development.

Projects

Learning projects from hackathons and self-study, not products. Each has notes on how it works, what was wrong with it and what I fixed.
