Senior Smart Contract Engineer · Solidity / EVM · Tokenization, Security & Full-Stack
I build the on-chain core of financial products, and stay until they are audited, shipped and used.
| $16M+ live TVL on platforms I engineer and operate | 15+ products shipped for clients and funds | 6 zero-to-one protocols led solo | EVM full-time since 2021 |

Security work starts on day one of every build: fuzz and invariant testing before features, static analysis and gas profiling as routine, audit-ready documentation written along the way. Most of my work is on tokenized assets, DeFi/RWA platforms, smart wallets and trading infrastructure.
- Tokenization · issuance-to-settlement design: reserve-attested minting, transfer restrictions and eligibility gating, corporate actions, epoch/NAV settlement. ERC-20/4626/7540, working knowledge of ERC-3643 and the ERC-1400 family.
- Security & testing · Foundry property-based/invariant/fuzz suites, Slither, Tenderly, external audit preparation and traceable findings remediation (on both sides of the audit).
- Smart wallets · on-chain WebAuthn (P-256) and RSA verification, factories and multi-signer modules, EIP-712/1271.
- Full-stack delivery · React/Next.js/Nuxt interfaces with typed contract hooks and simulate-first transaction pipelines, Node.js APIs, deployment and verification pipelines (Hardhat + Foundry).
AI-assisted engineering under systematic human review: no keys, addresses or sensitive logic ever exposed to external services.
