Led development of Gemach Onchain AI, a DeFi agent platform that simplifies complex blockchain interactions through an AI-powered interface. Integrated GoPlus Security's API suite into GBot AI, enhancing Web3 security infrastructure with real-time threat detection, NFT authentication, and phishing site recognition. Built automated workflows for token swaps, bridging, and liquidity provisioning across multiple blockchains with real-time market analysis and risk assessment capabilities.
Block #2025
Head · still being written
Developing complex smart contract systems for real estate tokenization and on-chain lending protocols that bring real estate on-chain and integrate it within DeFi rails. Building integration layers between real estate assets and DeFi infrastructure, advanced stablecoin mechanisms, and yield optimization strategies. Working on automated reward distribution systems, governance mechanisms, and cross-protocol composability features with existing DeFi ecosystems like Curve, Convex, and f(x) protocol. Focused on creating predictable, low-volatility strategies through real estate-backed lending and borrowing.

transferWithAuthorization()UChildEIP30090xf3c9…3ed1A UChild template for Polygon PoS tokens with transfers by signed authorization, so someone else can pay the gas.
A new UChild template for PoS Portal Tokens that integrates EIP-3009, allowing ERC-20 transfers with authorization. This upgrade supports meta-transactions, enabling users to delegate gas payments, batch transactions, and transfer tokens via signed authorizations, enhancing transaction flexibility and security.

invest()InvestmentManager0x9e82…7a24Stakes the bridge's excess ETH as stETH toward a target share, and redeems it when balances need it back.
Enhancement of LxLy bridge contract to enable staking of ETH through Lido. Adds an InvestmentManager role with permissions to manage ETH and ERC-20 assets in LxLy, stake excess ETH in stETH, and manage yield distribution. Key functions include invest() for staking ETH based on target percentages, and redeem() to adjust balances by redeeming stETH as needed.

propagateRoot()ScrollStateBridge0xfcf4…281fRelays World ID Merkle roots from Ethereum mainnet to Scroll, alongside the Optimism, Base and Polygon bridges.
Integration of the World ID State Bridge with the Scroll Bridge to enable cross-chain messaging. This integration enables propagation of World ID merkle tree roots from the WorldIDIdentityManager contract on Ethereum mainnet to Scroll, complementing existing support for Optimism, Base, and Polygon PoS. The implementation uses the OP bridge as a reference for Scroll, including xDomain messaging verification and deployment scripts.

Smart Contract Developer @ RAAC Protocol
about() → string
I'm a full-stack blockchain developer at RAAC Protocol, building real-estate tokenization and onchain lending. Before that, I led development of Gemach Onchain AI, a DeFi agent that translates chat into onchain actions across chains.
My focus is the unglamorous stuff: solid smart contracts, careful integration layers, and frontends that don't lie about what's happening underneath. I care about practice over polish, reps over rhetoric.
