Senior/staff software engineer focused on crypto-fintech infrastructure: backend systems, wallets, DeFi/trading rails, developer tooling, and protocol-adjacent product engineering.
Most recently: Kraken / Ink. Previously: Truffle, Opyn, Insrt, and Consensys.
I am interested in remote senior/staff IC roles where real assets, users, and production systems meet: backend/platform engineering, wallet infrastructure, DeFi/trading systems, Ethereum/L2 tooling, and pragmatic contract-to-hire or paid trial paths.
- parallel-revm-lab: Rust lab for deterministic parallel execution and real Base EVM storage-contention analysis. Includes a short Loom walkthrough.
- opstack-doctor: read-only diagnostic CLI for OP Stack and Superchain node operators.
- glamsterdam-compat-lab: deterministic Ethereum compatibility scanners for contracts, traces, indexers, and validator operators.
- Product-facing crypto infrastructure where correctness matters because value is moving.
- APIs, SDKs, services, and operational tooling that make complex onchain systems usable.
- Rust/TypeScript/Go systems around EVM, wallets, L2s, DeFi, trading, and developer platforms.
