What I'm looking for

I'm looking to build secure, scalable Web3 products where I can lead smart contract architecture, improve custody or exchange infrastructure, solve protocol security challenges, and collaborate with product and engineering teams.

At Fireblocks, I design and deploy Solidity smart contracts and Web3 infrastructure for institutional custody workflows, supporting more than 2,000 daily transactions with 99.99% uptime. I’ve reduced manual settlement steps by 40%, lowered smart contract gas consumption by 35%, and built secure multi-signature transaction flows across EVM networks.

Previously at Kraken, I led secure smart contract development for token listing and staking features handling more than $500M in total value locked with zero critical vulnerabilities. I built Ethereum dApp features, wallet connections, blockchain APIs, testing pipelines, and internal gas-estimation tools that improved release speed, incident detection, and infrastructure efficiency.

I bring 11+ years of software development experience spanning blockchain gaming, full-stack JavaScript applications, TypeScript services, and production engineering. I enjoy translating security, scalability, and protocol tradeoffs into reliable Web3 products while mentoring engineers and collaborating closely with product and frontend teams.
