Senior Web3 Protocol Engineer, Smart Contract Auditor & Fullstack Architect

🌐 Overview & Core Expertise

Senior Web3 Engineer and Open-Source Protocol Contributor with deep specialization in:

  • 🛡️ Smart Contract Security & Audits: EVM invariant fuzzing, Foundry PoC exploits, Slither static analysis, Defi liquidation models (Uniswap v4, Morpho, EigenLayer).
  • ⚡ Cross-Chain Protocol Development: Solana (Anchor/Rust), Arbitrum Stylus, ERC-4337 Account Abstraction, Zero-Knowledge proofs (Polygon ID / Circom).
  • 🎨 Enterprise Web3 UI/UX Design Systems: High-conversion dark-mode crypto interfaces, trading terminals, staking vaults (Figma Tokens, Tailwind CSS, React).
  • 🤖 Autonomous On-Chain Infrastructure: MEV arbitrage bots, Pyth/Chainlink oracle health monitors, automated DuneSQL analytics.

🛡️ Smart Contract Security Audits & Research ($475,000+ Prize Pools)

All audit findings include validated executable Foundry PoC test suites and mathematical invariant proofs:

Protocol & Scope Platform Severity Vulnerability Summary PoC Test Suite
Uniswap v4 Dynamic Hooks Code4rena High Concentrated Liquidity Invariant Violation on Custom Fee Swaps Foundry PoC
Morpho Blue Bad Debt Code4rena High Multi-Collateral Liquidation Insolvency on Non-Standard Oracle Spikes Foundry PoC
EigenLayer AVS Slashing Sherlock / Immunefi High Delegation Manager Inconsistent Unstake & Slashing Escalation Foundry PoC
Solana Perp DEX Engine Sherlock / Anchor Medium Pyth Oracle Staleness Window allows zero-slippage front-running Anchor Invariant
Groth16 ZK Privacy Pool CodeHawks Medium Scalar Field Underflow in Nullifier Hash Verification Circom PoC
