I secure billions in digital assets.
I build institutional-grade custody infrastructure that secures billions in digital assets. At Finoa, a regulated European custodian, I own core chain integrations end-to-end — from block parsing and UTXO/nonce management through HSM-backed signing and broadcast — for Bitcoin, Ethereum, and all Cosmos chains, and I designed Solana's integration architecture. 10+ L1s integrated in production.

What I Do
My focus is the full transaction lifecycle in a custody context: secure key management, signing-pipeline architecture, and reliable chain integrations.
Custody Infrastructure
Build the full custody transaction lifecycle — block parsing, UTXO and nonce management, HSM-backed signing, and broadcast — for a platform securing billions in digital assets.
Chain Integration
Own core integrations for Bitcoin, Ethereum, and all Cosmos chains, and integrated 10+ L1s overall. Unified six Cosmos codebases into one service that onboards a new network in about 20 minutes.
Security & Cryptography
Design signing and key-management flows and build open-source security tooling using standard primitives — Argon2id, HMAC-SHA256, AES-256-GCM, and Ed25519.
Selected Projects
Keygrain
Stateless password manager — derive, never store.
Multi-Agent Collaboration Framework
Protocol correctness enforced at the database layer.
