PROFILE
Patrick
Worked on the matter-labs/zksync-era repository, focusing on backend development and system stability over a three-month period. Addressed operational challenges by implementing robust error handling for proof data intake, specifically excluding batches missing object files in Google Cloud Storage to reduce log noise and prevent repeated failures. Tackled concurrency issues in the TEE prover by introducing atomic locking and exclusive table locks, ensuring only one instance processed each batch and improving resource efficiency. Delivered a feature enabling recoverable Ethereum-compatible signatures in the TEE prover, enhancing on-chain verification. Utilized Rust, SQL, and cloud storage integration to strengthen distributed system reliability.
