PROFILE
Lev Roitman
Lev contributed to the starkware-libs/sequencer repository by enhancing core backend and testing infrastructure using Rust and related tooling. He overhauled the StarkNet integration test harness, modularizing it into a standalone executable and introducing robust health checks with IsAliveClient, which improved reliability and reduced test flakiness. Lev also extended macro functionality to generate CLI arguments from struct fields, streamlining developer workflows and reducing boilerplate. Additionally, he improved the Apollo batcher by ensuring accepted transaction hashes are accurately tracked per block, increasing traceability and auditability. His work demonstrated depth in backend development, code generation, and integration testing within blockchain systems.

Apr 1, 2025April 2025: Delivered a correctness enhancement in the sequencer Apollo batcher by ensuring accepted transaction hashes are passed from sync_block to commit_block, enabling accurate per-block tracking of accepted transactions. Updated add_sync_block tests to collect and verify transaction hashes, increasing test coverage for batcher state. Commit: ae62ecdec2ca96004064c9837e2310571c0f20b5 (chore(apollo_batcher): add aceepted txs to sync_block). This improves batch integrity, traceability, and reliability of the sequencing pipeline, with direct business value in auditing and diagnostics.

Dec 1, 2024December 2024 — StarkNet integration test infrastructure overhaul for the starkware-libs/sequencer repo. Delivered a robust, modular end-to-end test harness with a dedicated module and standalone binary, simplifying execution and improving reliability. Removed outdated node compilation logic from the e2e path and migrated to pre-compiled binaries with clear identity checks. Implemented IsAliveClient-based readiness checks and comprehensive health mechanisms, replacing flaky timeout-based approaches. The work reduced build surface, cut test run times, and significantly lowered flakiness, enabling faster feedback for StarkNet integration cycles.
