What I'm looking for

I'm looking to build security-critical financial, blockchain, distributed-systems, or applied AI products where I can own architecture, solve ambiguous institutional requirements, and deliver reliable production systems.

I've built production financial infrastructure at SSV Labs, Zenrock, and Qredo, spanning validator systems, private Ethereum rollups, decentralized signing, institutional custody, and account-abstraction wallets.

At SSV Labs, I design validator and operator infrastructure for the SSV Network and contribute to Ethera’s private rollups, including permissioning, bridge routing, token controls, receiver-verification hooks, and cross-rollup execution. I also contributed to a two-bank proof of concept for atomic inter-bank M1 transfers using two-phase commit across private rollups.

Previously, I led ZrSign’s MPC-backed transaction-signing architecture at Zenrock and developed zenBTC multi-chain mint and redeem workflows. At Qredo, I built custody and signing products, institutional vaults, relayers, RBAC, multi-approval controls, and auditability features supporting institutional environments with $10B+ in assets.

I also build real-time data and applied AI systems, including Kafka and ClickHouse market-data platforms and a self-supervised PyTorch Transformer for financial behavior modeling. I bring end-to-end ownership across architecture, security reviews, audit coordination, reliability, and translating institutional requirements into production software.
