Smart Contract Engineer specializing in Solidity and DeFi systems on Ethereum and EVM chains. I build secure smart contracts, staking systems, token ecosystems, and Web3 applications with a focus on security, gas optimization, and production-ready architecture. I design and implement production-grade smart contracts for lending, staking, vesting, and token ecosystems โ with a strong focus on collateralization logic, liquidation safety, gas efficiency, and protocol-level security. I donโt build demos. I build systems where real value is at risk, and correctness, safety, and clarity matter. ๐น What I build DeFi lending protocols (collateral, LTV enforcement, health factor, liquidation, interest accrual) Staking & reward systems (finite reward pools, safe accounting, no infinite minting) Vesting contracts (cliff + linear vesting, founder & investor-safe designs) ERC20 token contracts (custom logic, controlled mint/burn, secure allowance handling) Security-focused smart contract architecture (reentrancy protection, access control, CEI pattern, protocol invariants) Smart contract integration (ethers.js, wallet interactions, transaction flows) ๐น How I work I think in protocol flows and invariants, not just individual functions I identify edge cases and security risks early I explain technical trade-offs clearly to non-technical stakeholders I write code that is testable, auditable, and maintainable Iโm comfortable working independently or with distributed teams ๐น What you can expect Clean, well-documented Solidity code Security-first design decisions Clear communication and realistic timelines Honest feedback on risks and limitations Long-term maintainability over shortcuts ๐น Letโs work together If youโre building a Web3 product that involves real asset flow, DeFi logic, or security-critical smart contracts, I can help you design and implement it correctly from day one. Iโm happy to review your idea, point out potential risks, and suggest a solid technical approach before any code is written.
