Worked on the matter-labs/zksync-era repository, delivering a major overhaul of the Airbender prover by migrating proof storage to Google Cloud Storage and refactoring the prover architecture for scalability and maintainability. Introduced a self-contained Cargo workspace for the prover server, enabling independent versioning and automated releases, while implementing bounded retry logic to improve workflow resilience. Addressed a mempool synchronization bug to prevent transaction stalling and enhanced CI/CD pipelines with Docker integration. Improved test reliability by stabilizing flaky Jest tests and adding polyfills for accurate error reporting, demonstrating proficiency in Rust, TypeScript, asynchronous programming, and backend development throughout the project.

Jul 1, 2026July 2026 monthly summary for matter-labs/zksync-era focused on improving test reliability and stabilizing the CI pipeline through targeted flaky-test mitigations and infrastructure fixes. Implemented a critical test infra polyfill to ensure accurate error reporting and prevent false negatives during migration and paymaster validations. Addressed multi-cluster flaky failures in the test suite to reduce CI noise and accelerate developer feedback loops.

Apr 1, 2026April 2026: Major feature overhaul of the Airbender prover and a migration to Google Cloud Storage (GCS) for proof storage, coupled with a codebase cleanup and a DB naming migration. The work centers on making proof handling more scalable, decoupled from the database, and easier to maintain, with new tooling to encode prover inputs.
