Sobre mí
I build and test Solidity smart contracts for DeFi and tokenized workflows—clean code, strong tests, and practical delivery.
What I can help you ship: • Smart contracts: ERC-20/721, vaults, marketplaces, presales, staking/yield, lending primitives • Testing: Foundry unit tests, fuzzing, invariants + CI-ready structure • Reviews/refactors: readability, access control, upgrade approach (if needed), gas-minded improvements • Web3 integration: TypeScript (ethers/web3), React/Next, Node.js APIs
How I work: 1) Quick scope + edge cases / threat model 2) Implementation using proven patterns (e.g., OpenZeppelin) 3) Tests + clear handover docs 4) Deployment support (scripts, verification, basic monitoring guidance)
Background: 8+ years in industrial automation + full-stack engineering (Java/Spring, Node/TS, PostgreSQL, Docker, Keycloak). I bring a reliability/production mindset to web3 builds.
