Working on production rollup infrastructure and custom rollup deployments, with a focus on the OP Stack, reliability, upgrades, migrations and security.
- Operate and upgrade ~80 OP Stack networks across mainnet, enterprise and testnet environments, including large-scale contract upgrades and hardforks.

- Built Rollup Canary, an internal system for continuously testing critical rollup flows such as deposits, withdrawals and upgrades, and extended it to test customer-specific behaviour.
- Work across OP Stack internals including op-node, op-geth, op-reth, op-batcher and associated proving, DA and sequencing infrastructure.
- Handle production incidents, security upgrades and customer-specific infrastructure issues across rollup deployments.
- Work on custom rollup infrastructure and integrations including ZK proving systems, stablecoin (USDC, AUSD) infrastructure, and bundlers.
