Designed and implemented end-to-end smart contract architecture from scratch, including custom ERC20 tokenomics and ERC1155 NFT-based position tracking system. Built token swap mechanism enabling users to convert assets into protocol tokens for investment in early-stage Web3 startups with automated yield distribution. Developed ERC1155 NFT contracts to tokenize investment positions, enabling transparent on-chain tracking of user stakes and proportional yield allocation. Engineered cross-chain functionality using ZetaChain’s omnichain infrastructure, allowing seamless multi-chain asset deployment and management.

Contributed to multiple open-source DeFi and gaming protocols across Cairo and Solidity ecosystems managing a total TVL of over $100k, delivering production-ready code reviewed by senior protocol engineers. Implemented features and bug fixes for decentralized applications, focusing on gas optimization, security patterns, and protocol-specific logic in smart contract codebases. Submitted high-quality contributions, demonstrating ability to work asynchronously with distributed teams and meet protocol development standards.

Delivered custom Solidity and Cairo smart contracts for 7+ clients across Gaming, DeFi, NFT, and tokenization projects, including AMM protocols, staking mechanisms, and token vesting contracts managing a total TVL of over $50k. Conducted smart contract security audits and gas optimization reviews for early-stage Web3 startups, identifying critical vulnerabilities and reducing deployment costs. Architected and deployed end-to-end blockchain solutions with comprehensive testing suites (Foundry/Hardhat), frontend integration, and on-chain deployment across Ethereum, Polygon, and other EVM chains.
