Hi, I'm Alejandro 👋

⚡ Web3 × AI Engineer  ·  🔨 Shipping on EVM (Ethereum · Base) & Starknet  ·  📍 Panamá 🇵🇦

---

I build at the intersection of smart contracts and AI agents — writing and auditing contracts on Ethereum, Base, and Starknet, and using MCP + agentic workflows to make development and security reviews faster.

This profile is my working portfolio. Every repo here is real work, and I document the technical lessons as I go — bugs I found and fixed, architecture decisions, and patterns I learned shipping.

• 🔭 Currently completing a Master's in Blockchain Systems & AI Engineering (CodeCrypto)
• 🛡️ Building open-source security tooling for Cairo/Starknet (see cairo-audit-skill below)
• 🦀 Learning Rust → moving into Solana development next
• 🎓 4× Anthropic certifications — Claude, MCP & agentic workflows
• 💬 Open to remote Smart Contract / Protocol / Web3 Security roles (LATAM & global)
