👋Hello world, I'm
Full-stack engineer & smart-contract developer building practical web3 solutions. I work in Solidity, TypeScript, and the spaces between chains.

About me
Background, current focus, and why I do what I do.
I'm a Full-stack Blockchain Developer currently 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.
Looking for product-minded teams where I can ship things that compound.

Selected work
A modern web3 application that combines AI capabilities with blockchain transactions, enabling smart contract interactions and cross-chain operations through an intuitive chat interface
A cross-chain forwarder enabling 6551 contracts to seamlessly call instances on either Ethereum or zkEVM via the LxLy bridge. Functionality includes bidirectional call forwarding between Ethereum and zkEVM.
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.
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.
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 will use the OP bridge as a reference for Scroll, including xDomain messaging verification and deployment scripts.
Career
A few teams, a lot of contracts.
Smart Contract Developer
Developing complex smart contract systems for real estate tokenization and on-chain lending protocols. Building integration layers between real estate assets and DeFi infrastructure, advanced stablecoin mechanisms, and yield optimization strategies. Working on automated reward distribution systems and cross-protocol composability features with existing DeFi ecosystems like Curve, Convex, and f(x) protocol.
Full Stack Blockchain Developer
Integrated GoPlus Security's API suite into GBot AI, enhancing Web3 security infrastructure with real-time threat detection, NFT authentication, and phishing site recognition
Smart Contract Developer
Contributed to multiple bounties for THE LLAMAS community, focusing on cross-chain messaging, token integration, and security enhancements. Worked on integrating the Polygon zkEVM LxLy bridge for cross-chain messaging, developed Scroll support for the World ID State Bridge, and implemented EIP-3009 and permit functionality for PoS Portal tokens.
Stack
Curated, not exhaustive — these are the ones I'm fluent in.
Notes
Process docs, deep-dives, references — the kind of thing I wish I'd had on day one.
Reference guide for the development, testing, audit and deployment workflow on RAAC Protocol — Hardhat config, Solidity standards, security patterns, gas optimisation, coverage thresholds, audit checklist and deployment pipeline.
