What I'm looking for

I’m looking to build and own web3 product front-ends end-to-end—shipping fast with React/TypeScript, collaborating closely with engineers on secure wallet workflows, and improving UX in high-traffic systems.

I’m a Senior Web3 front-end engineer with 9+ years of experience, focused on shipping reliable user experiences and performant interfaces with React, TypeScript, and modern web stacks. I’ve owned complex wallet and DeFi front-end systems, shaping product architecture from initial client design through production delivery.

At Vultisig, I owned the cross-chain wallet client and helped scale secure, multi-chain capabilities by building shared wallet logic across clients and extracting it into a reusable product SDK. I also worked on MPC threshold signing, replacing single-seed wallets with multi-device security across EVM, UTXO, Solana, and other chains for Vultisig.

Earlier roles strengthened my delivery breadth: at Terraform Labs, I shipped DeFi features for Anchor Protocol using React and TypeScript, built front-ends for NFT protocols, and led Enterprise Protocol on multiple Cosmos chains—reaching peak treasury of ~$65M. I’ve also built NFT and wallet flows with React for Zerion and developed production onboarding and back-end APIs (Node.js, GraphQL, PostgreSQL) with AWS/DynamoDB and infrastructure using Terraform.
