Led the migration from Optimism to World Chain by developing a centralized bridge handling over $100M in assets and serving 10M+ users, deploying critical infrastructure smart contracts (e.g., Safe, Uniswap), and collaborating with external vendors for network support.

Built a transaction relayer service (OpenZepplin Defender replacement) that consumed 50% of Optimism blockspace and reduced cost by $300k/yr

Maintained 99.9% uptime as sole maintainer of World App's off-chain infrastructure, supporting 10m users and over 1m daily transactions

Interviewed, onboarded, and led the crypto infrastructure team from 1 to 5 engineers, reducing average incident response time by 50%

Provided technical vision and leadership while architecting a new backend, resulting in a 40% boost in developer productivity

Tech lead for implementing a threshold signature schema (TSS) for a chain agnostic

retail wallet. Created a microservice that facilitates decentralized key generation and

signing. Created a signing client for mobile and browser extension.

Led team of 3 engineers in developing MetaMask Institutional (MMI), the first

institutional-grade multisig browser wallet (partnership with ConsenSys). Generalized MMI to work for all EVM chains.

Built a defi-specific policy engine (velocity, whitelist, approver thresholds).

Migrated multisig repo from Truffle to Hardhat and formalized a smart contract

deployment pipeline that is used to manage and deploy different versions of our

multisig wallet contract.

Audited ETH multisig smart contract wallets to add support for sending and receiving

NFTs (ERC721 / ERC1155).

Owned cross-platform refactor for EIP1559 transaction building and parsing in

response to the London ETH hard fork with no downtime.

Optimized transaction broadcasting logic to handle 10x volume increase through

BitGo’s ETH wallets.

Built a challenge-response protocol that allowed users to authenticate using

cryptographic signatures.

Developed a client library to upload and manage public keys using the W3C

DID standard.

Developed applications to provide all critical functions of a stablecoin business including smart contract deployment/ integration, admin/compliance portal, and integrations with banking partners.

Designed the admin portal to allow back office users to handle all user management functionality (KYC/Compliance) and mint/redeem operations.

Integrated smart contracts with the backend, allowing users to automatically mint ERC-20 stablecoin by wiring our banking partner.
