Designed, developed, and audited smart contracts across EVM, Solana, Aptos, Stellar, and multi-chain ecosystems; authored detailed technical specifications and deployment scripts using Foundry and Hardhat. Identified 1 Critical, 25+ High, 12+ Medium severity vulnerabilities across 10+ solo engagements on DeFi primitives including stablecoins, lending markets, vesting launchpads, insured yield vaults, and P2P bridges. Integrated The Graph subgraphs, JSON-RPC providers, and IPFS storage layers for dApp backend infrastructure, enabling on-chain data indexing and decentralized file handling. Expanded smart contract development scope to Move (Aptos/Sui), Rust (Solana/Anchor, Soroban), and Cairo (Starknet) beyond primary EVM expertise. Contributed findings on Sherlock and Code4rena audit contests; reviewed codebases ranging from validator registries to cross-chain bridge logic and multi-protocol lending systems. Developed Foundry-based test suites with fuzz testing and invariant checks; built custom exploit PoCs to demonstrate economic impact of identified vulnerabilities.

Web3 Security Researcher with hands-on experience auditing smart contracts and decentralized protocols across EVM, Solana, and Move ecosystems. Skilled in identifying high-impact vulnerabilities through manual review, fuzz testing, invariant analysis, and exploit development, with experience across DeFi, staking, lending, DEXs, and cross-chain systems
