Building production blockchain applications since 2018. Currently at Gnosis; previously co-founder & CTO at impactMarket.
I build across the boundary between on-chain and off-chain systems: smart contracts, backend services, blockchain indexing, and user-facing applications.
Built the cashback system for Gnosis Pay users from scratch. My work also includes Envio indexing infrastructure, Circles smart-contract integrations and balance calculations, and Gnosis App features in Svelte.
Co-founded impactMarket and led engineering while remaining hands-on across smart contracts, backend services, indexers, and web/mobile applications.
Built products spanning universal basic income, microcredit, Libera Wallet, and Learn & Earn. The platform reached 45,000+ UBI beneficiaries across ~30 countries, with $3M+ distributed on-chain.
Built a no-loss lottery prototype using Zama FHE, Safe smart accounts, and gas sponsorship. Combines encrypted deposits and winnings with social login and a mobile-first interface.
Ethereum Sepolia prototype. Yield is currently mocked through sponsor-funded prizes.
Built and contributed to open-source Ethereum tools, including a reusable smart-contract library, a Solidity documentation generator, and a dApp starter kit.
