Blockchain Developer

I'm a blockchain developer who turned grant funding into production code that real projects use.

Started coding in 2019, I've spent the last year delivering for major blockchain foundations: TON Foundation and Polkadot's Web3 Foundation. As the 2nd highest contributor to the TON plugin for ElizaOS, I built staking modules, NFT marketplace integrations, and comprehensive testing infrastructure that's now adopted by 12+ projects in the ecosystem.

For Polkadot, I co-developed their Level 2 grant-funded plugin, implementing on-chain data feeds, governance queries, and subsidized transactions that reduced costs by 60%. All my work maintains >95% test coverage and follows production-grade standards.

I specialize in TypeScript, React, Node.js, and Web3 integrations across TON, Polkadot, and Ethereum ecosystems. US citizen based in Sicily, fluent in English and Italian, looking for remote opportunities with teams building the next generation of blockchain infrastructure.
