Security-focused Smart Contract Developer with proven experience identifying high-impact vulnerabilities in public audits. Combines hands-on expertise in modern blockchain development (Solidity, Foundry) with a 5-year background in professional systems management. Adept at designing and deploying secure, smart contracts with advanced testing methodologies, including fuzzing and invariant testing.

🔍 Core Expertise:

• Smart Contract Auditing: Practical knowledge of different attack vectors like reentrancy, integer overflows, oracle manipulation, and gas inefficiencies.
• Blockchain & Web3: Solidity, Foundry, EVM, DeFi, Off-chain Oracles, Blockchain Architecture, DevOps.
• Security & Testing: Unit Testing, Fuzz & Invariant Testing, Attack Vector Analysis.
• Tools & Platforms: Foundry, Static analyzer tools (Slither, Aderyn), Git, GitHub, Tenderly.

🚀 Current Focus:

• Performing economic audits and security assessments for DeFi protocols.
• Advancing expertise in assembly, formal verification and gas optimization for smart contracts.
• Contributing to audit competitions like CodeHawks and Code4rena to enhance security skills.

• Project:
  • Decentralized Lottery
    • A provably fair, automated, and decentralized lottery smart contract for Ethereum.
      Built with Foundry and powered by Chainlink VRF, Chainlink Automation, and Chainlink Price Feeds.
    • This project started as the Cyfrin Foundry Smart Contract Lottery from the Cyfrin Updraft course, then evolved with new features, improved architecture, and more robust testing.
• Audit Competitions:
  • Participated in two public smart contract security contests, demonstrating a strong adversarial mindset.
  • Ranked #239 in CodeHawks, with identifying valid high & low-severity vulnerabilities.
  • Engaging in Code4rena audits to strengthen high-stakes smart contract security expertise.
• Cyfrin Updraft Challenge NFTs / CTFs:
  • Exploited vulnerable smart contracts by developing and executing scripts for various attack vectors, including reentrancy, integer overflows, oracle manipulation, and Delegatecall.
  • Demonstrated security expertise by minting all challenge NFTs of Foundry and Security courses through smart contract exploitation.
  • On-Chain Proof: View minted NFTs on ZKsync Mainnet (link)
