Emanuele Gaspari Castelletti · DeFi Engineer / Smart Contract Developer (Solidity) · Verona, Italy 🇮🇹
Solidity Engineer with 6 years building EVM protocols across DeFi and other domains. I design production-grade, upgradeable, role-scoped contracts with rigorous testing (unit, invariant, fuzz) and own the lifecycle from specs to code to reviews to deployment, keeping releases reliable over time.
Security-minded and fluent in best practices, OpenZeppelin libraries and proxy patterns (UUPS / Beacon / Transparent). I set technical roadmaps and long-term architecture for scalability, modularity and security, run audit remediation with security vendors, and maintain production runbooks with timelock/multisig upgrade procedures.
Before Web3 I spent years as a startup co-founder, CTO and lead backend developer (PHP/Symfony, REST APIs, AWS), which is where my focus on reliable backends and clean APIs comes from.
- Engineered and shipped in production an EVM protocol that reached $732M TVL within 5 months at KernelDAO (source code · BSC mainnet deployments)
- Led the product lifecycle end to end, hands-on from requirements to mainnet
- Delivered audited smart contracts with security vendors and shipped remediations; executed timelock and multisig upgrades without user disruption
- Embedded risk controls and test harnesses into integrations touching staking and lending
