Site Reliability Engineer · Web3 / Blockchain RPC Infrastructure · Rust + Go

3 years operating bare-metal blockchain RPC infrastructure at scale: 70+ ledgers (Ethereum, Solana, L2s), hundreds of nodes across three regions, 99.9%+ uptime.

I build production tooling in Rust and Go, debug node clients across execution and consensus layers, choreograph hardforks, and maintain internal patched forks.
