⚡ 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
• 🎓 8× Anthropic certifications — Claude, MCP & agentic workflows
• 💬 Open to remote Smart Contract / Protocol / Web3 Security roles (LATAM & global)

Non-custodial escrow for atomic ERC20 swaps between two parties who don't trust each other — either both legs of the swap settle, or neither does. CEI pushed down to the file layout: libraries own the effects, the contract owns the checks and interactions. Live on Ethereum Sepolia with verified contracts · 32 Foundry tests (100% coverage on core contracts) + 6 Playwright E2E tests against a real chain.

Moving into smart contract security auditing. Current focus:

• CodeHawks — working through First Flights; findings published as I complete them
• cairo-audit-skill — open-source Agent Skill for AI-assisted Cairo audits (resuming Jul–Aug 2026)
• Audit-minded by default in my own code: strict CEI, custom errors, SafeERC20, 100% coverage on core contracts
