Kevin Small
@kevinsmall
Staff blockchain engineer designing secure, compliant Solidity and DeFi architectures.
What I'm looking for
I’m a hands-on lead engineer with 20+ years designing and implementing enterprise solutions, with the last 8 years focused on Solidity, blockchain development, and DeFi. I specialize in building robust, secure, and scalable systems that meet stringent regulatory requirements, backed by deep smart contract architecture experience.
Most recently, I worked as Staff Solidity Engineer at XMTP Labs, owning Solidity smart contract architecture for a decentralized messaging protocol, including tokenomics and staking design across Ethereum, Base, and L3 chains. Previously, as Head of Blockchain at PV01, I led cross-chain token, vault, and oracle architecture for tokenized debt instruments, handling security design, threat modelling, audits, integrations, and smart contract delivery that secured “tens of millions of USD” in TVL.
I also bring a systems approach to engineering workflow—adapting development toward spec-driven, deterministic validation and reproducible environments for agent-assisted delivery. Beyond product work, I create open-source blockchain data visualisation and apply security-first thinking across the full lifecycle of blockchain operations.
