► Engineered production smart contracts for Genius V2 a DeFi protocol whose economic model is driven by Golden Ratio (PHI) mathematics, implementing inflation schedules, auction mechanics, and vault issuance logic. ► Implemented the ERC-1618 custom token standard with a cross-supply accounting registry handling token transfers and accounting across multiple supply pools simultaneously. ► Implemented PHI-based economic formulas using overflow-safe integer arithmetic, validating correctness under edge-case inputs while preserving protocol solvency. ► Designed a PHI-based inflation adjustment system embedded in the day summarization loop, reducing reward supply on a mathematically predictable schedule, analogous to Bitcoin's halving but using the golden ratio as the decay factor. ► Optimized daily state storage to fit entirely within a single 256-bit slot through deliberate variable packing, achieving 18–24% gas savings across multiple core functions. ► Enforced a strict single cross-contract call per function architecture to minimize external call overhead, reducing gas costs and attack surface across the protocol. ► Designed and implemented dual auction mechanisms for standard and collateral commitments with trustee-based permissions, PHI-derived bid increments, and automated settlement formulas. ► Architected and deployed the foundation's first DAO from scratch, enabling Grantor-specific governance actions including DeFi credit issuance and collateral management within the Genius protocol economy

► Served as the sole Blockchain Developer, working directly under the CTO to develop and deploy RWA smart contracts using ERC-20, ERC-721, ERC-3643, and ERC-1155 token standards► Architected and deployed a MERN stack DApp for a crypto marketplace, integrating smart contract front-ends for the company's RWA platform ► Built bundle-sniping detection scripts and implemented an anti-bundle-snipe mechanism, protecting ERC-20 token launches from front-running attacks ► Designed a modular on-chain payment system enabling users to pay for VPN services using any supported ERC-20 token ► Authored clear technical specifications that accounted for Ethereum ecosystem constraints, reducing mid-sprint scope changes ► Developed comprehensive Foundry test suites c

► Designed and deployed smart contracts across DeFi, NFT, and DID verticals for multiple clients, working across Ethereum mainnet and L2 networks (Polygon, zkSync) ► Built full-stack DApps using React.js, Next.js, and MERN stack with Wagmi/Moralis integration, bridging Web2 back-ends with Web3 smart contract data

► Developed whitelisted ERC-721/721A NFT contracts with Merkle tree-based access control across multiple projects ► Ensured smart contract logic accurately reflected project tokenomics requirements ► Supported integration of blockchain back-end services with front-end applications
